从China供应商批发进口3-Aminopyridine — FOB条款

3-Aminopyridine (CAS 462-08-8, molecular formula C5H6N2) from Wuhan Yuan Cheng GongChuang Technology Co.Ltd is a heterocyclic aromatic amine positioned at the 3-position on the pyridine ring. The supplier indicates industrial-grade purity of 98-99% and packages the material in 25 kg drums for industrial handling. This fine chemical functions as a nucleophilic intermediate owing to the amino group located meta to the ring nitrogen, creating distinctive reactivity patterns compared with 2-aminopyridine or 4-aminopyridine isomers.

The compound exists as a crystalline solid at room temperature with characteristic pyridine base properties. The amino group participates in diazotisation, acylation, and condensation reactions, while the ring nitrogen enables metal coordination and hydrogen bonding interactions. Standard industrial synthesis routes include aminolysis of 3-bromopyridine or reduction of 3-nitropyridine. Buyers should confirm which manufacturing route the supplier employs, as residual halide or nitro intermediates affect downstream applications in sensitive pharmaceutical syntheses.

Primary demand comes from active pharmaceutical ingredient manufacturers, agrochemical formulators, and specialty dye producers. The material serves as a building block for antihistamines, antivirals, herbicides, and fungicides. Research institutions also procure smaller quantities for method development and scale-up studies. For import purposes, the material requires hazmat classification and proper SDS documentation. Buyers should confirm exact purity, melting point, and residual solvent specifications with the supplier before committing to bulk orders.

Wuhan Yuan Cheng GongChuang Technology Co.Ltd is located in Qianjiajie, Wuhan, Hubei Province, China, postal code 432000. Wuhan is a major chemical and pharmaceutical manufacturing hub in central China with established logistics networks for fine chemical exports. The supplier's trust tier is listed as harbour, with zero response rate and zero average response hours recorded, so direct communication channels must be tested before relying on this platform for time-sensitive procurement.

The company positions itself as a supplier of pharmaceutical and agrochemical intermediates, with 3-aminopyridine represented as a core product line. No information is provided about manufacturing facility GMP status, ISO certification, R&D capabilities, year of establishment, or annual turnover. Buyers should request facility audit reports, quality management system certificates, and export experience documentation. The supplier address is in a commercial district rather than an industrial zone, suggesting possible trading rather than manufacturing operations, which buyers should verify.
