3-Chloro-2-hydroxypropyltrimethyl Ammonium Chloride丨CAS 3327-22-8

3-Chloro-2-hydroxypropyltrimethyl ammonium chloride (CAS 3327-22-8) is a quaternary ammonium compound widely used in the textile, paper, and chemical industries. It serves primarily as a cationic reagent for modifying cellulose, starch, and other polysaccharides to enhance water solubility, dye affinity, and antistatic properties. In textile applications, it is employed to produce cationic cotton and other fabrics with improved dye uptake and colorfastness. In the paper industry, it functions as a wet-strength agent and retention aid, improving paper durability and print quality. Additionally, it is used as an intermediate in the synthesis of cationic surfactants, antimicrobial agents, and polymers with tailored surface properties, making it valuable for personal care products, coatings, and water treatment chemicals.

The benefits of 3-chloro-2-hydroxypropyltrimethyl ammonium chloride arise from its dual functional groups and cationic nature. The quaternary ammonium group imparts strong positive charge, enabling efficient binding to negatively charged substrates such as cellulose, fibers, and anionic polymers. The hydroxypropyl functionality provides flexibility, water solubility, and reactivity for further chemical modifications. Its high reactivity, chemical stability, and compatibility with aqueous and organic systems make it easy to incorporate into various industrial processes. The compound enhances performance characteristics such as wet strength, dye retention, antistatic behavior, and antimicrobial activity, improving both product functionality and durability.
