从China供应商批发进口5-Amino-2, 4, 6-Triiodoisophthalic Acid — FOB条款

5-amino-2,4,6-triiodoisophthalic acid (C8H4I3NO4) is a triiodinated aromatic dicarboxylic acid serving as the foundational intermediate for nonionic iodinated X-ray contrast media. This compound features three iodine atoms substituted at the 2, 4, and 6 positions of the isophthalic acid ring, with an amino group at position 5, delivering the high iodine content essential for radiographic opacity. Jp Fine Chemical Co., Ltd supplies this material from Shenzhen, Guangdong, with purity typically above 98% as indicated in their pharmaceutical-grade specification.

The material is manufactured as a crystalline powder and requires sealed, moisture-controlled packaging to maintain hydrolytic stability. The free acid form, as distinct from its acid chloride derivative, offers specific reactivity profiles for amidation and esterification routes in multi-step synthesis. Typical pharmaceutical synthesis employs this intermediate for producing iopamidol, iohexol, and related second-generation contrast agents where the triiodinated benzene core must be introduced with precise regiochemistry and minimal residual impurities.

Buyers include API manufacturers, radiopharmaceutical contract manufacturers, and diagnostic imaging companies in Europe, North America, and Asia-Pacific. The compound ships under controlled conditions with documentation for pharmaceutical intermediate use. Confirm with Jp Fine Chemical Co., Ltd the exact certificate of analysis per batch, residual solvent profile, and whether DMF or CEP support is available for regulated markets.

Jp Fine Chemical Co., Ltd operates from Shenzhen, Guangdong Province, with registered addresses in both Nanshan District's High-Tech Zone and Baoan District's Baoyuan Building on Baoyuan Road. The supplier holds a harbor trust tier on the platform, though their response rate is recorded at 0.00% with an average response time of zero hours, indicating no quote responses have been generated through this channel. The listing presents the company as a source for pharmaceutical-grade iodinated intermediates with international export capability.

The supplier profile does not disclose manufacturing site GMP status, ISO certifications, batch capacity, or specific regulatory filings such as DMF or CEP documentation. No employee count, annual revenue, or client references appear in the available data. Buyers should verify directly with Jp Fine Chemical Co., Ltd their quality management system, whether they operate under cGMP for API intermediates, and their experience with regulatory audits for contrast media raw material supply.
