从China供应商批发进口3, 4-Dichloroaniline — FOB条款

3,4-dichloroaniline (C6H3Cl2NH2, molecular weight 162.02 g/mol) is an aromatic amine intermediate with the chlorine substituents at the 3- and 4-positions on the benzene ring relative to the amino group. The material supplied by Changshan County Hongyun Chemical Co., Ltd. from their facility in Changshan County, Zhejiang Province, is positioned for industrial synthesis applications where this regiochemistry is critical to downstream product formation. The compound presents as a crystalline solid at ambient temperature with characteristic odour typical of aromatic amines, and requires handling protocols consistent with its classification as a hazardous chemical substance under international transport regulations.

Industrial-grade 3,4-dichloroaniline is typically manufactured via catalytic hydrogenation of the corresponding nitro precursor, followed by purification to achieve standard commercial purity levels. The material is sensitive to oxidation and light exposure, necessitating storage under inert atmosphere or in sealed containers with appropriate stabilisation. Typical impurities monitored in commercial lots include isomeric dichloroanilines (particularly 2,3- and 2,4-isomers), residual solvents from the manufacturing process, and trace heavy metals. The product finds primary utility as a diazotisation component for azo dye synthesis and as a building block for chloroaniline-based agrochemical active ingredients where the 3,4-substitution pattern confers specific biological activity.

Buyers in the dyes and pigments sector utilise this intermediate for the production of disperse and direct dyes, particularly those requiring enhanced light-fastness properties. The agrochemical industry employs it in the synthesis of herbicidal compounds including urea and carbamate derivatives. Pharmaceutical applications include use in the manufacture of certain anti-microbial and anti-parasitic agents. Trade in this material typically involves drum packaging (200 kg net, standard steel construction with epoxy phenolic lining) or woven polypropylene bags with polyethylene liner for solid formulations. Shipment from Zhejiang Province ports (Ningbo or Shanghai) follows UN 2811 classification for toxic solids, organic, n.o.s. with appropriate hazard communication documentation.

Changshan County Hongyun Chemical Co., Ltd. is located at No.1 Zhengshen Road, Eco-Industrial Park District, Changshan County, Quzhou, Zhejiang Province, China (postal code 324200). The supplier is classified under the imported tier within the marketplace trust framework, holding harbour-level verification status. The available profile data indicates no response activity, with a recorded response rate of 0.00% and average response time of zero hours, which prospective buyers should factor into their communication expectations and due diligence planning when initiating enquiries.

The supplier's operational focus, as inferred from their product listing, centres on aromatic amine intermediates for the B2B chemical manufacturing sector. No verified information regarding establishment year, production capacity, employee count, annual revenue, or specific client base is present in the source data, and none should be assumed. Buyers are advised to request direct documentation of manufacturing licences, environmental compliance certificates, and quality management system credentials when engaging with this supplier. The physical address in Zhejiang Province, a region with established chemical industry infrastructure, may offer logistical advantages for port access and domestic Chinese transport connectivity.
