从China供应商批量进口3, 4-Dichloro-Nitrobenzene

3, 4-dichloro-nitrobenzene from Changshan County Hongyun Chemical Co., Ltd. is a nitroaromatic intermediate with molecular formula C6H3Cl2NO2, characterised by adjacent chlorine substitution at the 3 and 4 positions relative to the nitro group at position 1. This structural arrangement renders the compound reactive toward nucleophilic aromatic substitution, making it valuable in synthetic routes to dyes, agrochemical actives, and pharmaceutical precursors. The supplier, located in Changshan County, Quzhou, Zhejiang province, positions the material as stable under normal handling and storage conditions.

Industrial grades of 3, 4-dichloro-nitrobenzene typically vary by purity and impurity profile, with standard specifications referencing GC assay, individual impurity limits, and moisture content. The nitro group activates the aromatic ring toward reduction to the corresponding aniline, a common downstream transformation, while the two chlorine atoms provide handles for further substitution or elimination chemistry. Buyers in the agrochemical sector particularly value this scaffold for herbicide and fungicide synthesis, where the regiochemistry controls biological activity. Thermal stability and compatibility with common organic solvents are typical properties supporting multi-step process integration.

Target purchasers include agrochemical intermediate traders, fine chemical manufacturers, and custom synthesis houses serving pharmaceutical development programmes. The listing indicates flexible minimum order quantities and mentions FOB and CIF as available shipment terms, though exact quantities and port designations require direct confirmation. Given the supplier's harbour trust classification and zero response rate metric, prospective buyers should initiate technical dialogue to validate current stock availability, lead time, and whether the company provides regulatory support documentation such as REACH pre-registration or TSCA inventory status for North American import.

Changshan County Hongyun Chemical Co., Ltd. is headquartered at No.1 Zhengshen Road, Eco-Industrial Park District, Changshan County, Quzhou 324200, Zhejiang province, China. The location within an eco-industrial park suggests zoning for chemical manufacture with environmental compliance infrastructure, though the listing does not detail specific environmental permits or emissions data. The supplier holds imported tier and harbour trust classifications, with a 0.00% response rate and zero average response hours recorded, indicating no active engagement history on the sourcing platform. Buyers must rely on direct outreach to establish communication reliability and technical competence.

The company profile does not disclose year of establishment, registered capital, number of employees, annual turnover, other product portfolio items, or named domestic and international customers. No quality management system certifications, patents, or export licence details are provided. For a first transaction, buyers should request audited financials or bank references, and verify the legal existence of the entity through the Zhejiang Administration for Industry and Commerce. Site visits or third-party factory audits are advisable given the limited digital footprint and the chemical nature of the products offered.
