Import 3-Amino-6-Iodopyrazine-2-Carboxylic Acid — Buy in wholesale FOB from Supplier in China

3-amino-6-iodopyrazine-2-carboxylic acid (CAS 875781-48-9) is a heterocyclic pharmaceutical intermediate with the molecular formula C5H4IN3O2. It carries a pyrazine core substituted with amino, iodine, and carboxylic acid functional groups at the 3, 6, and 2 positions respectively. The compound is supplied with a purity of 95% or higher, making it suitable for demanding synthetic applications in drug discovery and development. Its molecular weight of 265.01 g/mol and halogenated structure render it reactive toward palladium-catalysed cross-coupling and nucleophilic substitution protocols common in medicinal chemistry.

The iodine substituent at C-6 provides a handle for Suzuki, Sonogashira, and Heck couplings, while the amino group at C-3 can be acylated, alkylated, or diazotised to access diverse chemical space. The carboxylic acid at C-2 enables amide and ester formation, or decarboxylative transformations. Standard storage requires protection from light and moisture to prevent oxidative degradation of the iodinated ring. Typical packaging(patch) packaging for such intermediates includes amber glass bottles or sealed aluminium-laminate bags with desiccant, though buyers should confirm the exact packaging configuration with Shanghai Hanhong Chemical Co., Ltd. directly.

This intermediate finds primary use in the synthesis of kinase inhibitors, antiviral agents, and other bioactive molecules where the pyrazine scaffold appears in approved drugs. Buyers include pharmaceutical companies running medicinal chemistry programmes, contract research organisations (CROs), and academic laboratories. The compound is traded globally from Shanghai, with Incoterms such as FOB or CIF available subject to negotiation. Minimum order quantities, lead times, and certificates of analysis should be confirmed directly with the supplier, as these are not fixed in the listing data.

Shanghai Hanhong Chemical Co., Ltd. is located at Room 207, Zonghe Building, Jiachuan Road, Shanghai 200237, China. The supplier operates on an imported tier basis within the marketplace, with a trust tier classified as harbour. The response rate is recorded at 0.00% and the average response time is zero hours, which indicates that direct communication with this supplier may require persistence or alternative contact methods beyond the platform messaging system.

The company supplies fine chemicals and pharmaceutical intermediates to global buyers, with this listing focused on halogenated pyrazine derivatives for research and industrial synthesis. No verified ISO certifications, specific manufacturing capabilities, client references, or years in operation are stated in the available profile data. Buyers should conduct independent due diligence, request a certificate of analysis for each batch, and verify the supplier's quality management system before committing to orders.
