1.
Differentiated compliance grading and access standards Products are divided into high-purity reagent grade, optoelectronic electronic grade and industrial synthesis grade. The EU enforces REACH and SVHC hazardous substance controls, while pharmaceutical intermediate categories follow European and American GMP raw material management standards. Strict controls are imposed on HPLC main content, residual free benzaldehyde, inorganic ash, heavy metals, moisture, residual solvents and isomer impurities. English COA, SDS, certificates of origin and third-party chromatographic test reports must be provided for each batch. Unqualified products or documentation will result in customs detention and termination of cooperation with downstream pharmaceutical and optoelectronic manufacturers.
2.
3.
Minor deviations in indicators lead to batch project scrapping Insufficient purity sharply reduces optoelectronic catalytic efficiency and shifts the color tone of organic dyes; residual aldehyde impurities interfere with closed-loop pharmaceutical synthesis. Tetraphenylporphyrin powder undergoes slow oxidative discoloration when exposed to air or high temperatures. High temperature and humidity during transoceanic sea freight degrade product quality, invalidating batch laboratory trials by buyers.
4.
5.
Benzaldehyde and pyrrole are hazardous fine chemical raw materials with volatile prices driven by environmental production restrictions and plant maintenance Core synthetic raw materials experience price fluctuations due to domestic chemical environmental regulations and plant maintenance. European and American local mass production is extremely limited, leading to heavy reliance on domestic Chinese fine synthesis capacity. Standard sea freight plus customs clearance cycles take 5–7 weeks. Demand surges during peak stocking seasons for new material research and pharmaceutical intermediates, driving one-time raw material price hikes of 20%–35%. Frequent customs inspections and tight shipping space for fine powder chemicals risk production line and laboratory shutdowns due to material shortages.
6.
1.
Complete supporting compliance documents by grade for one-stop customs review Separate production lines for high-purity reagent, pharmaceutical and industrial grades, fully equipped with REACH registration and third-party residual solvent testing materials. English HPLC COA and SDS are issued on demand, with parameters aligned to European and American pharmacopoeia and reagent standards. Support is provided for customer import filing and factory/laboratory audits.
2.
3.
Sealed condensation + multi-stage recrystallization purification + low-temperature drying process to lock core physicochemical parameters Closed propionic acid catalytic synthesis, multiple alcohol recrystallization steps to remove by-products and residual raw materials, and low-temperature vacuum drying to eliminate solvents. Full-item chromatographic testing by SGS third-party laboratories is conducted before delivery, with narrow internal control tolerances for main content. Products are vacuum-lined with aluminum foil and packed in 25kg light-shielded fiber drums to isolate oxygen and light, eliminating oxidative discoloration during sea transit.
4.
5.
Long-term price-locking agreements + safety stock in European bonded warehouses 6–12 month annual supply long-term agreements lock base prices with annual price adjustments capped at ≤5%. Safety stock covering 2–3 months of demand is maintained at bonded warehouses in core European ports; standard orders are delivered locally within 3–5 working days. Emergency small trial samples for research are shipped by compliant air freight and arrive within 48 hours.
6.
1.
Price surcharges for small-batch purchases and middlemen inflate end-user costs Small factories and laboratories typically order 100–300kg at a time, while the industry standard minimum order quantity is 500kg with a 10%–18% surcharge for small lots. Counterfeit products mixed with inorganic salts and cheap organic powders flood the market, causing catastrophic declines in catalytic and color performance.
2.
3.
Errors in feeding ratios and synthesis processes lead to high finished product yield losses Buyers cannot distinguish high-purity reagent grade from crude industrial grade; improper feeding ratios and reaction temperature control result in substandard downstream synthetic product purity, with comprehensive raw material losses exceeding 8%.
4.
5.
Prevalent counterfeiting & heavy upfront capital pressure Low-priced adulterated products disrupt the market; transoceanic order cycles range from 45–60 days, with small orders delayed an additional 2–3 weeks. Full advance payment requirements tie up working capital.
6.
1.
No premium for orders starting at 100kg, tiered ex-factory prices direct from manufacturers Minimum order threshold lowered to 100kg at factory direct prices; volume discounts apply for 500kg orders, with an additional 4% price reduction for 1-ton lots. Direct manufacturer supply eliminates middlemen, cutting end-user procurement costs by over 20%.
2.
3.
Free sample provision + full English on-site technical guidance Free samples ranging from 10g to 1kg are provided, accompanied by English feeding ratio manuals and light-shielded storage control guidelines. Remote selection guidance reduces production losses to below 3%.
4.
5.
Regional consolidated container shipping + flexible settlement + full batch traceability Consolidate scattered orders into shared containers to shorten lead times to 30–35 days. Each shipment includes third-party HPLC quality inspection reports and product traceability codes to eliminate counterfeiting. Settlement terms of 30% advance payment + 70% against copy of bill of lading ease cash flow pressure.
6.
1.
Zero tolerance for residual solvents, heavy metals and organic by-products in clean formulations Pharmaceutical API and OLED optoelectronic materials impose strict limits on residual alcohols, aldehydes, heavy metals and organic by-products. Ordinary crude products fail European and American pharmaceutical registration and optoelectronic safety compliance testing and cannot enter high-end supply chains.
2.
3.
Trace impurities in low-addition formulations cause catalytic failure and color spot defects Formulations require extremely low additive loadings; trace impurities trigger catalytic deactivation and pigment speckles, while high-temperature long-distance transportation accelerates oxidative degradation of powders.
4.
5.
Rapid iteration of new product formulas requires frequent custom trial lots of 50g–20kg, which cannot be matched by standard mass production scheduling.
6.
1.
Ultra-high-purity multi-stage recrystallization grades meeting clean compliance thresholds Three rounds of deep organic solvent recrystallization thoroughly remove synthetic by-products and residual solvents, with dedicated pharmaceutical/optoelectronic chromatographic test reports provided. Impurity indicators outperform EU limit values.
2.
3.
Inert gas passivation modification of powders for long-term oxidation resistance Products are packed under nitrogen inert atmosphere to boost anti-oxidation performance, resisting discoloration under low-temperature light-shielded storage and extending shelf life of downstream finished goods.
4.
5.
Custom trial orders starting at 50g with priority scheduling for R&D Custom purity and particle size specifications available on demand; dedicated R&D production lines with priority scheduling to fully support laboratory formulation testing by overseas clients.
6.
1.
Agglomeration and reduced catalytic activity when compounded with metal salts and various additives Crude low-quality TPP contains excessive impurities, causing agglomeration when mixed with metal coordination raw materials and rendering entire batches of composite catalysts inactive.
2.
3.
Open workshop storage leads to slow oxidative discoloration upon air exposure, degrading feedstock quality.
4.
5.
Price hikes for large-volume centralized procurement erode profit margins; uninterrupted full-year production lines incur massive downtime losses from stockouts, with demand for compatibility with automated closed feeding systems.
6.
1.
Optimized high-purity grade dedicated to compounding with improved formulation compatibility Compatibility testing conducted for mainstream coordination catalysis and pigment compounding formulas; optimized powder particle size ensures uniform mixing without agglomeration with metal salts and additives.
2.
3.
Anti-oxidation modified grades + technical guidance for light-shielded closed storage Anti-oxidation passivated product lines launched, paired with standardized light-shielded oxygen-isolated storage protocols to reduce oxidative losses.
4.
5.
Tiered volume discounts + annual supply guarantees + industrial bulk packaging Additional price reductions for ton-scale and above orders with full-container shipments lowering unit costs; annual supply contracts lock production capacity. Packaging options include 25kg fiber drums and bulk bags compatible with automated closed feeding equipment.
6.
1. Stocking multiple grades (high-purity reagent, pharmaceutical, industrial) ties up large amounts of working capital.
2. Lack of laboratory testing equipment prevents self-inspection of HPLC purity and residual solvents, leading to risk of purchasing counterfeit inferior goods. Failed end-user experiments or production trigger compensation claims and damage channel reputation.
3. Cumbersome customs declaration for scattered fine powder shipments; oxidative discoloration under open storage/transport creates complicated after-sales handling.
1.
Mixed consolidated orders across grades with third-party repackaging and drop-shipping support Mixed-grade consolidated shipments with no single-item minimum order requirements; light-shielded constant-temperature third-party repackaging and drop-shipping at overseas warehouses enable distributors to operate with zero inventory.

Tetraphenylporphyrin powder with HPLC purity ≥ 99.8%;
Residue of each transition metal ion including iron, copper, zinc and nickel ＜ 0.2 ppm;
Moisture content ≤ 150 ppm, ash content ≤ 0.05%;
Uniform regular acicular crystal form without amorphous powder;
Excellent solubility in dichloromethane and toluene at room temperature; 5% concentration solution shows no precipitation or turbidity after standing for 72 hours;
Thermal decomposition temperature ≥ 420 ℃;
Purity and crystal form remain unchanged after 18 months of sealed storage away from light at room temperature.
Challenges in achieving ultra-high purity and deep metal ion removal: Tetraphenylporphyrin is synthesized via the condensation reaction of benzaldehyde and pyrrole. Major impurities include reaction by-products, unreacted raw materials and metal ions from synthetic catalysts. Conventional recrystallization cannot reduce transition metal residues to below 0.2 ppm, while repeated purification will sharply lower product yield and alter crystal forms. It was difficult to balance purification efficiency, product yield and crystal form stability.
Complex regulation of regular crystal forms: The crude product after synthesis tends to form a mixture of acicular, granular and amorphous crystals. Mixed crystal forms directly impair solubility, film-forming quality in coating processes and fluorescence performance. Slight changes in crystallization temperature, cooling rate and solvent system will alter crystal morphology, requiring highly precise control over crystallization parameters.
Strict requirements for long-term solution stability: Affected by light and trace impurities, Tetraphenylporphyrin molecules tend to aggregate and cause precipitation or turbidity in organic solvents. It was necessary to strictly control impurities and optimize post-treatment processes to ensure the long-term stability of high-concentration solutions.
Stringent standards for thermal and storage stability: The macrocyclic conjugated structure is prone to oxidative deterioration under light, high temperature and aerobic conditions. The 18-month long storage period demanded high-standard packaging to block light, oxygen and moisture.
Complicated compliance with EU regulations for research chemicals: The CLP classification and labeling, hazard identification, basic toxicological data and full-component analysis reports have strict requirements. Ordinary domestic chemical test reports cannot be used directly, and re-testing, translation and certification procedures were highly cumbersome.
Strict control over cross-border dangerous goods transportation: The fine powder is prone to dusting and moisture absorption, subjecting it to stringent rules on classification, packaging, light-proof and constant-temperature maritime transportation for cross-border dangerous goods.
High requirements for batch consistency of small-batch high-value products: The purity, metal residue and crystal form of each batch must be highly uniform, bringing great challenges to quality control during mass purification.
For ultra-high purity and metal removal: We adopted a combined process of stepwise condensation synthesis, multi-stage gradient recrystallization and chelating metal removal. Ultra-high-purity raw materials were used for the reaction. A special metal chelating and extraction system was applied to remove transition metal ions, followed by gradient recrystallization with solvents of different polarities. The final product achieved an HPLC purity of 99.86%, all metal ion residues below 0.15 ppm and an ash content of 0.032%.
For crystal form regulation: A single solvent system was adopted, together with a programmed slow cooling crystallization process. The cooling rate and final crystallization temperature were precisely controlled, and crystallization was conducted in a light-shielded static environment. The final product presented uniform regular acicular crystals with even particle size distribution.
For solution stability: The finished products were protected by inert gas to isolate oxygen, and trace polar impurities were thoroughly removed. Standard-concentration solution tests confirmed no precipitation or turbidity after 72 hours, fully meeting solubility requirements.
For thermal and storage stability: The products were vacuum-sealed and nitrogen-filled away from light to isolate illumination, oxygen and moisture. Accelerated aging tests verified that product performance did not degrade within 18 months.
For EU compliance: We completed hazard classification and full-range testing in accordance with EU CLP and REACH regulations, compiled a full set of English compliance documents and spectral reports, which were reviewed and filed by professional chemical consultants in Switzerland.
For storage and transportation: Special light-proof, heat-insulated and moisture-proof packaging was adopted, and constant-temperature light-proof containers were used for maritime transportation to avoid exposure to light and high temperature.
Excessive impurities and residual oligomers in the powder caused molecular aggregation, precipitation and turbidity in organic solutions.
Metal ions and conjugated structure defects interfered with fluorescence performance, resulting in insufficient and fluctuating fluorescence intensity.
Mixed crystal forms led to inconsistent solubility and poor stability in application.
The product had weak anti-oxidation and anti-photolysis capabilities, and was prone to discoloration and purity degradation under conventional storage conditions.
The powder was highly hygroscopic, and high humidity in the warehouse further accelerated deterioration and precipitation.
Replace the products with high-purity Tetraphenylporphyrin processed via multi-stage recrystallization to completely remove reaction by-products and oligomers and eliminate solution precipitation and turbidity.
Adopt products with deep metal ion removal to eliminate the interference of impurities on conjugated systems and fluorescent groups, and stabilize fluorescence intensity.
Uniformly apply products with single acicular crystal form to guarantee consistent solubility from the source.
Use light-proof sealed nitrogen-filled packaging for finished products. Store goods in cool and dark warehouses with relative humidity controlled below 40%, and finish repackaging quickly to reduce open exposure time and avoid oxidation and discoloration.
Establish an incoming inspection system for raw materials, conducting random sampling tests on HPLC purity, metal ion content and crystal forms, and rejecting unqualified products.

Core raw materials are benzaldehyde and pyrrole, which undergo closed-loop condensation in propionic acid solvent to form high-end fine intermediates for pharmaceutical and optoelectronic industries. Overseas manufacturers are concentrated in the United States, Japan and South Korea. Pyrrole raw materials are subject to strict control and environmental restrictions, with discontinuous small-batch synthesis and limited mass production capacity. Conventional orders have a lead time of 60–90 days, and raw material prices frequently rise due to pyrrole chemical plant maintenance and hazardous chemical regulations.
In China, fine chemical parks feature mature supporting facilities for pyrrole and benzaldehyde. Scaled-up intermittent rectification and purification processes have been implemented, with specialized manufacturers maintaining regular small-batch stock. High-purity domestic grades are priced 30%–45% lower than imported European and American counterparts. Domestic products are mainly exported to European and American research institutes, optoelectronic material manufacturers and catalytic formulation enterprises, with complete logistics support for air freight of small consignments and sea freight of full containers.
Products are classified into industrial catalytic grade, optoelectronic reagent grade, high-purity research grade and pharmaceutical intermediate grade. Mandatory supporting documents include MSDS/SDS, EU REACH registration and TSCA notification. High-purity reagent exports are accompanied by COA and HPLC test reports; full heavy metal testing reports are provided on demand for some pharmaceutical intermediate orders.
Small overseas workshops mostly lack REACH registration, leading to high risks of customs detention in the EU. Top-tier domestic suppliers provide full sets of compliance documents with shipments, minimizing customs clearance compliance risks.
Grading is determined by HPLC purity, free impurities, moisture and metal residues: conventional 95% industrial grade, 98% reagent grade, and ≥99.5% ultra-high-purity optoelectronic grade. Custom metal-free TPP and pharmaceutical-specific grades with tightly controlled trace impurities are available.
Overseas manufacturers rely on column chromatography for purification, with customization cycles exceeding 45 days. Domestic producers can adjust synthesis ratios and adopt multi-stage recrystallization purification. Small trial samples ranging from 5g to 1kg can be quickly packed, while mass production is delivered in 25kg fiber drums.
Purity and residual pyrrole/benzaldehyde directly affect photocatalytic efficiency and yield of OLED intermediates. Our fine chemical technical staff provide remote guidance on feeding ratios, dissolution & precipitation, and formulation stability issues.

1. HPLC main content: 95.0% for industrial grade, 98.0% for reagent grade, ≥99.5% for ultra-high-purity optoelectronic grade. Insufficient purity drastically reduces photosensitive and catalytic activity.
2. Residual free pyrrole + benzaldehyde: ≤0.1% for high-purity grades; excessive residues cause material discoloration and increased catalytic side reactions.
3. Loss on drying (moisture): ≤0.3% for all grades, ≤0.1% for ultra-high-purity grades.
1. Appearance: Premium grade presents dark purple to purple-black crystalline powder with uniform color and no caking of white foreign impurities; inferior products contain yellowish-brown raw material impurities.
2. Solubility: Qualified products dissolve in dichloromethane, chloroform and toluene, with slight solubility in alcohols and water. Insoluble agglomerates indicate excessive impurities.
1. Heavy metals (Pb, As, Cd, Fe): ≤10ppm per single element for pharmaceutical and optoelectronic grades; relaxed to 50ppm for industrial catalytic grades.
2. Ignition residue (inorganic salt residue): ≤0.05% for ultra-high-purity grades.
1. Photosensitive properties: Compliant UV-Vis characteristic absorption peaks for photocatalysis, photosensitive resins and dye-sensitized solar cells.
2. Coordination capacity: Capable of complexing with iron, zinc, cobalt and other metals to form metalloporphyrins without unidentified impurities interfering with coordination reactions.
3. Storage stability: No discoloration or decomposition under light-shielded ambient storage for 12 months.
Packaged in light-shielded sealed fiber drums; store in cool and dry areas away from strong light and oxidants. Classified as general cargo for sea transportation with no special hazardous packaging requirements.
