从China供应商批发进口5-Chloro-8-Hydroxyquinoline — FOB条款

5-Chloro-8-hydroxyquinoline (C9H6ClNO, CAS 773-76-2) is a chlorinated heterocyclic aromatic compound belonging to the quinoline family, supplied by Yixing Hongbo Fine Chemical Co., Ltd. from their facility in Yixing, Jiangsu Province, China. The molecular formula indicates a bicyclic structure with chlorine substitution at the 5-position and hydroxyl functionality at the 8-position, conferring both metal-chelating capability and reactivity for further derivatisation. The compound is offered at typical industrial purities of 95% to 99%, with the exact assay, melting point range, and residual moisture content to be confirmed directly with the supplier prior to order placement. It is packaged in fiber drums or steel drums, standard formats for moisture-sensitive fine chemicals in bulk pharmaceutical and agrochemical trade.

This quinoline derivative functions as a bidentate chelating ligand through its phenolic hydroxyl and ring nitrogen, forming stable complexes with transition metals including copper(II), iron(III), and aluminium(III). The chloro substituent at C-5 modulates the electron density of the heteroaromatic system, influencing both the pKa of the hydroxyl group (typically around 7.0-7.5 for the conjugate acid) and the stability constants of its metal complexes. In pharmaceutical synthesis, it serves as a building block for antimalarial analogues, antibacterial agents, and kinase inhibitors; in agrochemical applications, it contributes to fungicidal and bactericidal formulations. The compound is light-sensitive and requires storage under inert atmosphere or amber packaging to prevent oxidative degradation, a standard precaution for hydroxyquinoline derivatives.

Primary buyers include active pharmaceutical ingredient (API) manufacturers, contract research organisations (CROs), agrochemical formulators, and academic laboratories requiring gram-to-kilogram quantities of specialised heterocyclic intermediates. The supplier's location in Yixing, within the Yangtze River Delta chemical manufacturing corridor, positions it near Shanghai port for maritime export. Importers should verify the specific grade (research, technical, or GMP-compliant), certificate of analysis (CoA) availability, and whether the material is handled under IATA or IMO dangerous goods protocols, as halogenated phenolic compounds may trigger environmental hazard classifications depending on concentration and formulation.

Yixing Hongbo Fine Chemical Co., Ltd. is located at Nancao, Yixing 214217, Wanshi, China, within the Jiangsu Province chemical manufacturing belt. The supplier holds an 'imported' tier classification and a 'harbor' trust designation on the sourcing platform, with a recorded response rate of 0.00% and average response time of zero hours, indicating that direct communication data for this profile is either not captured or not yet established. The company operates in the fine chemicals sector, specifically serving the supply of chlorinated heterocyclic intermediates for downstream pharmaceutical and agrochemical industries, though no verified production capacity, reactor type, or reactor count is disclosed in the available profile information.

The listing provides chemical identity data including CAS registry number and molecular formula, but omits specific manufacturing accreditations, quality management system certifications (such as ISO 9001), environmental compliance statements, or customer references. The supplier address places it approximately 120 km west of Shanghai, with access to the Yangtze River Delta logistics network, though importers should independently confirm export licence status, customs registration, and dangerous goods handling permits. No stated employee count, annual revenue, year of establishment, or parent company affiliation appears in the source material, and none should be assumed.
