Hexadecyltrimethylammonium Bromide (1631-Br/CTAB)
CAS 57-09-0
Hexadecyltrimethylammonium Bromide (CAS 57-09-0) is a high-purity cationic quaternary ammonium surfactant widely used in molecular biology, nanotechnology, chemical synthesis, cosmetics, and pharmaceutical applications. It appears as a white crystalline powder with mild amine odor, soluble in hot water, ethanol, and chloroform. With an assay of ≥99.0%, low free amine content (≤0.3%), and pH 5.0–7.0 (1% aqueous solution), it serves as an essential reagent for CTAB-based DNA/RNA extraction from plants and polysaccharide-rich samples, a structure-directing template for mesoporous materials like MCM-41 and gold nanorods, an efficient phase transfer catalyst, a hair conditioning and antistatic agent in personal care products, and a bactericidal disinfectant and drug delivery surface modifier in pharmaceutical formulations. Available in various packaging sizes with consistent quality and competitive pricing from Sunly factory.
>> Main Uses
Hexadecyltrimethylammonium Bromide (1631-Br/CTAB, CAS 57-09-0) is widely used in molecular biology for DNA and RNA extraction from plants, bacteria, and fungi by effectively removing polysaccharides and polyphenols; in nanotechnology as a soft template for synthesizing mesoporous silica materials such as MCM-41 and as a shape-directing agent for controlling the aspect ratio of gold nanorods; in the chemical industry as an efficient phase transfer catalyst for two-phase organic reactions and as a cationic emulsifier and dispersant in industrial formulations; in cosmetics and personal care as a hair conditioner, antistatic agent, and bactericide in shampoos, creams, and disinfectant wipes; and in pharmaceutical and medical applications as a broad-spectrum antiseptic against gram-positive bacteria and a surface modifier for drug delivery systems and liposome formulations.
