Import 3,5-Dichlorobenzoyl Chloride — Buy in wholesale FOB from Supplier in China

3,5-Dichlorobenzoyl chloride (CAS 2905-62-6, formula C7H3Cl3O) is an acyl chloride derivative of 3,5-dichlorobenzoic acid, supplied by Speranza Chemical Co., Ltd. from Shenzhen, China, with stated purity of 98%. This compound presents as a colourless liquid or crystalline solid at ambient conditions, with a melting point of 28 °C and boiling point of 135-137 °C at 25 mm Hg, indicating significant volatility even under moderate vacuum. The acyl chloride functional group imparts high reactivity toward nucleophiles, making this material suitable for amide and ester bond formation in pharmaceutical and agrochemical synthesis.

The molecular weight of 209.46 g/mol and three chlorine substituents (two aromatic, one acyl) classify this as a hazardous material under UN3261, Class 8 (corrosive), Packing Group III, requiring careful handling and transport documentation. Industrial production typically involves thionyl chloride or oxalyl chloride conversion of the corresponding acid, with residual SOCl2 or HCl content representing critical quality parameters not specified in the source data. Standard specifications for acyl chlorides in fine chemical trade include acid chloride assay by titration, free acid content, and appearance clarity at specified temperature.

Buyers of 3,5-dichlorobenzoyl chloride from Speranza should confirm current availability, packaging format (200 kg drums cited as standard), and whether the material is stabilized with additives to suppress HCl liberation during storage. The compound's use as a synthesis intermediate in herbicide and pharmaceutical manufacturing demands consistent purity and low moisture content, as trace water hydrolyzes the acyl chloride to the parent acid. Due to Speranza's recorded zero response rate, prospective purchasers should establish viable communication before relying on listed specifications for production planning.

Speranza Chemical Co., Ltd. maintains its registered address at 1809, Yingfeng Center, No.6 Yinwei Road, Longgang District, Shenzhen 518000, Guangdong, China. The harbor-tier status indicates basic platform verification, though the zero percent response rate and zero average response hours suggest that platform-based inquiry may not yield timely communication. For acyl chloride procurement, direct engagement through the Shenzhen address or verified trade show contact is likely more reliable than depending on automated platform messaging.

The supplier lists 3,5-dichlorobenzoyl chloride alongside the corresponding acid, suggesting a focused product line in dichlorinated aromatic intermediates, but the profile does not disclose manufacturing capacity, R&D capability, or regulatory filings such as FDA drug master file or REACH pre-registration. The proximity to Shenzhen's chemical logistics infrastructure, including port access and customs brokerage services, represents a practical advantage for international buyers, though Speranza's role as manufacturer, distributor, or agent remains unverified in the source data. Buyers should request facility audit access or third-party manufacturing verification for GMP or ISO-compliant applications.
