从China供应商批发进口3,5-Dichlorobenzoic Acid — FOB条款

3,5-Dichlorobenzoic acid (CAS 51-36-5) is a halogenated aromatic carboxylic acid with the molecular formula C7H4Cl2O2 and a molecular weight of 191.01 g/mol. This white crystalline powder melts at 184-187 degrees Celsius and serves as a building block in organic synthesis, particularly for agrochemical and pharmaceutical intermediates. Speranza Chemical Co., Ltd., based in Shenzhen, Guangdong Province, lists this material with a stated purity of 99%. The product is classified non-dangerous for transport, though standard precautions for handling aromatic acids and chlorinated organics apply.

The compound consists of a benzoic acid core substituted with chlorine atoms at the 3 and 5 positions, conferring electrophilic character useful in cross-coupling and nucleophilic aromatic substitution reactions. Typical industrial grades for such intermediates range from 98.0% to 99.5% purity, with the lower limit often acceptable for bulk synthesis steps and the higher grade reserved for API precursor work. Moisture content is typically controlled below 0.5% to prevent hydrolysis of activated derivatives. Standard packaging for Chinese fine chemical exporters is 25 kg net in fibre drums with polyethylene liner, though Speranza Chemical notes flexibility to customer requirements. Storage at 2-8 degrees Celsius preserves stability against oxidative degradation and sublimation, which can occur at ambient temperature in poorly sealed containers.

Buyers of 3,5-dichlorobenzoic acid include custom synthesis houses, agrochemical formulators, and pharmaceutical manufacturers developing chlorinated benzamide or benzonitrile derivatives. Common applications span herbicide intermediates (notably for protox inhibitors), dye chemistry, and specialty polymer additives. Importers should verify the supplier's batch-specific certificate of analysis, residual solvent profile, and heavy metal limits before committing to pharmaceutical-grade volumes. The response rate for this listing shows no recorded engagement, so direct enquiry to confirm current inventory, manufacturing capacity, and regulatory documentation (including EINECS 200-092-4 compliance) is advisable.

Speranza Chemical Co., Ltd. maintains its registered address at 1809, Yingfeng Center, No.6 Yinwei Road, Longgang District, Shenzhen 518000, Guangdong Province, China. The company operates from a commercial office building in one of China's primary chemical trading and innovation hubs, with proximity to Shenzhen Port for export logistics. The supplier holds a harbor trust tier on this platform, indicating a baseline verification status, though the response rate stands at 0.00% with zero recorded average response hours. This absence of engagement history means buyers should treat initial contact as exploratory and request direct references or transaction records.

The listing provides no information on manufacturing site location, production scale, quality management system certifications, or in-house analytical capabilities. Speranza Chemical's profile does not specify whether it operates as a manufacturer, trader, or hybrid entity, nor does it disclose years in operation, employee count, or key clientele. Buyers should ask directly for a manufacturing licence, ISO certification status, and batch retention sample policy. The EINECS registration cited for the product suggests EU regulatory awareness, but importers should independently verify REACH compliance and secure a current safety data sheet before shipping.
