从China供应商批量进口4-Pyridylmercapto Acetyl Chloride Hydrochloride

4-Pyridylmercapto acetyl chloride hydrochloride (PMAC) is aheterocyclic organosulfur compound used as a key intermediate in pharmaceutical synthesis, particularly for introducing pyridylthio moieties. Jinzhou Zhongshi Chemical Industry Co., Ltd supplies this compound with a molecular formula of C7H8ClNOS, and it is typically offered in a white to off-white crystalline powder form.

The compound’s high reactivity stems from the acyl chloride and thiol groups, making it suitable for derivatisation in medicinal chemistry. Industry-standard purity for PMAC is ≥98% by HPLC, with residual solvents such as dichloromethane or ethyl acetate typically below 0.1%. Melting point is usually in the range of 120 - 125°C, and the compound is stable under dry, inert conditions.

Pharmaceutical and agrochemical manufacturers utilise PMAC in the synthesis of APIs and crop protection agents, where the pyridylthio group confers specific biological activity. Buyers in China typically source it in 25 kg fibre drums with inner PE bags, and shipments are arranged under CIF or FOB terms. Confirm moisture sensitivity and handling precautions with the supplier.

Jinzhou Zhongshi Chemical Industry Co., Ltd is located at Xizi Jinzhou City in Hebei Province, China. The company specialises in the production and export of pharmaceutical intermediates and fine chemicals, catering to the needs of the global life sciences and agrochemical industries.

The supplier holds an imported-tier status with a harbor trust tier, indicating verified business credentials and export capabilities. While the current response metrics are not available, the company’s focus on niche chemical compounds suggests a capacity to meet specific technical requirements and provide tailored export documentation.
