Product Usage

Hexadecyl Trimethyl Ammonium Bromide (CTAB for short), with CAS No. 1119-94-4, is a cationic surfactant. It appears as white crystalline powder, easily soluble in polar solvents such as water and ethanol, with stable chemical properties, and has multiple functions including sterilization, emulsification and antistatic. Its core application is as a phase transfer catalyst in organic synthesis, accelerating the reaction between aqueous and organic phases, and improving reaction efficiency and product purity. It is also widely used in daily chemical, pharmaceutical, water treatment and other fields, serving as a bactericidal disinfectant to kill bacteria and fungi quickly, and as an emulsifier and antistatic agent to improve product performance, being an indispensable functional chemical raw material in many fields with small dosage and significant effect.
