从China供应商批量进口3-Chloro-2-Hydroxypropyltrimethyl

3-Chloro-2-hydroxypropyltrimethylammonium chloride (CHPTAC) is a quaternary ammonium cationic etherifying agent supplied by Dongying J&M Chemical Co., Ltd. from Shandong Province, China. The material functions as a reactive cationic monomer that introduces permanent positive charges onto cellulose, starch, and synthetic polymer substrates through etherification. The compound is typically supplied as an aqueous solution with active content around 69%, though buyers should confirm the exact concentration and CAS registration (302-17-0 for the chloride salt) directly with the supplier before formulation.

The product structure contains both a reactive epoxide precursor (the chlorohydrin form) and a trimethylammonium group, enabling efficient grafting onto anionic substrates under alkaline conditions. Typical industrial grades exhibit pH values between 3 and 5 in aqueous solution, with density near 1.15 g/cm³ at 20°C. Purity specifications vary by application; paper-grade CHPTAC generally permits higher residual epichlorohydrin and dichloropropanol levels than personal-care or pharmaceutical grades, where impurity limits may fall below 10 ppm total. Dongying J&M Chemical does not declare specific grade designations or certificate coverage in its listing, so buyers must verify whether supplied material meets their sector's regulatory thresholds.

Primary applications span paper internal sizing (as a cationic starch modifier), textile finishing, water-treatment flocculant synthesis, and personal-care polymer production. The reagent reacts with guar gum, cellulose derivatives, and other polysaccharides to yield cationic polymers with enhanced substantivity to negatively charged surfaces. Industrial buyers typically procure CHPTAC in bulk aqueous form to avoid handling dry powders; common packaging includes 250 kg plastic drums, IBC totes, or flexitanks for large-volume orders. Importing from Dongying requires attention to Chinese hazardous chemical export licensing, proper UN classification for transport, and confirmation of Incoterms and lead time, none of which are specified in the available data.

Dongying J&M Chemical Co., Ltd. is located at Room 1219, Zisheng Mansion, Zibo Road, Dongying 257000, Shandong Province, China. The supplier is classified within the 'imported' tier and holds a 'harbor' trust designation on the platform, indicating a baseline verification level rather than advanced audit status. The listing shows zero response rate and zero average response hours, which suggests either recent platform enrolment, inactive account management, or data collection limitations rather than operational scale. Buyers should treat direct communication testing as essential before relying on this supplier for time-sensitive orders.

The company profile provides no information about establishment year, registered capital, production capacity, quality-management certifications (such as ISO 9001), or specific manufacturing site details. No client references, export history, or third-party audit statements are included. The address points to a commercial office building rather than an industrial plant, which may indicate trading or agency activity rather than direct manufacturing. Prospective buyers should request a factory audit, business licence, and product-specific certificates of analysis before committing to bulk orders.
