从China供应商批发进口4,4'-Oxybis(Benzene Sulfonyl Chloride) (Obsc) — FOB条款

4,4'-Oxybis(Benzene Sulfonyl Chloride) (OBSC) from Jiaxing Kingvolt Chemical & Export Co., Ltd. is a sulfonyl chloride compound supplied at a minimum purity of 99%, verified under controlled manufacturing conditions. The chemical, with the molecular formula C12H8Cl2O5S2, is presented as a stable, off-white to light yellow crystalline powder, soluble in common organic solvents such as dichloromethane and acetone. Its reactivity and stability make it a preferred intermediate for synthesizing sulfone-containing compounds in industrial processes.

As an industrial-grade reagent, OBSC is typically used in the production of pharmaceuticals, agrochemicals, and specialty chemicals where sulfone functional groups are required. The compound’s typical melting point ranges between 128 and 132°C, and it exhibits low volatility under standard conditions. Industry-standard handling procedures classify it as a moisture-sensitive material, requiring storage in a dry, inert atmosphere to prevent hydrolysis of the sulfonyl chloride groups.

This OBSC grade is sourced from Jiaxing in Zhejiang province, a hub for fine chemical manufacturing in China. Buyers in pharmaceutical and agrochemical sectors use it as a key intermediate for active ingredient synthesis, while dye manufacturers employ it to introduce sulfone linkages in organic pigments. The supplier offers bulk drum packaging, with logistics arranged under hazmat-certified conditions to comply with international chemical shipping regulations.

Jiaxing Kingvolt Chemical & Export Co., Ltd. operates from 2002, A Building, Yaocheng Plaza, No.1520, East Zhongshan Road in Jiaxing, Zhejiang province. The company is classified under the harbor trust tier, indicating compliance with baseline verification standards for chemical exporters in China. Its address places it in a commercial district of Jiaxing, a city recognized for its chemical manufacturing and export infrastructure.
