Import 3, 5-Dichlorobenzoic Acid — Buy in wholesale FOB from Supplier in China

3,5-Dichlorobenzoic acid (CAS 51-36-5) is a halogenated aromatic carboxylic acid with the molecular formula C7H4Cl2O2 and molecular weight 191.01 g/mol. This white to almost-white crystalline powder features two chlorine substituents at the 3 and 5 positions of the benzoic acid ring, a substitution pattern that confers distinctive reactivity in electrophilic aromatic substitution and metal-catalysed coupling reactions. Speranza Chemical Co., Ltd. supplies this material from their Shenzhen location, with the product specified at 99% purity and packaged in standard 25 kg drums or customised to buyer requirements.

The compound is principally employed as a synthesis intermediate in pharmaceutical and agrochemical manufacturing, serving as a building block for diaryl ether formation through Ullmann or Buchwald-Hartwig coupling, and for Grignard or organolithium reagent generation at the carboxylic acid or after reduction. The melting point of 184-187 degrees Celsius indicates a highly crystalline material with strong intermolecular hydrogen bonding in the solid state; this thermal property is useful for rapid purity assessment but requires handling precautions as the powder can become electrostatically charged during milling or transfer. Storage at 2-8 degrees Celsius preserves chemical integrity, though the material is classified as non-dangerous for transport, simplifying warehousing requirements compared to reactive organometallics or pyrophoric reagents.

Primary end-users include custom synthesis laboratories, contract research organisations, and manufacturers of active pharmaceutical ingredients where the 3,5-dichloro substitution pattern appears in final drug structures or probe compounds. The acid functionality permits direct amidation, esterification, or decarboxylative coupling, while the chlorine atoms serve as orthogonal handles for further functionalisation. When negotiating with Speranza Chemical, confirm the exact polymorph or crystalline form supplied, as different crystal habits affect dissolution rates in subsequent reactions, and verify whether batch-specific nuclear magnetic resonance (NMR) and high-performance liquid chromatography (HPLC) data accompany each delivery.

Speranza Chemical Co., Ltd. is located at 1809, Yingfeng Center, No.6 Yinwei Road, Longgang District, Shenzhen, Guangdong Province, China. The company holds harbor trust tier status, with a response rate of 0.00% and average response time of 0 hours recorded in the source data, indicating limited or unmeasured engagement rather than confirmed inactive status. The Shenzhen address places the supplier in one of China's major chemical trading and export logistics hubs, with proximity to Yantian Port and Hong Kong border crossings for international shipment.

The company name and product focus suggest specialisation in fine chemicals and organic intermediates rather than bulk commodity chemicals. No verified manufacturing certifications, ISO registrations, or specific quality management accreditations appear in the source data. The Yingfeng Center address indicates office-based operations rather than integrated manufacturing, so buyers should clarify whether Speranza Chemical produces the 3,5-dichlorobenzoic acid in-house or sources from third-party manufacturers in Guangdong or neighbouring chemical industrial zones. Direct verification of production capability, R&D infrastructure, and regulatory compliance history is advisable before committing to volume orders.
