Hexadecyltrimethylammonium chloride, commonly known as cetyltrimethylammonium chloride (CTAC), is a quaternary ammonium compound widely used as a cationic surfactant in fabric softeners, hair conditioners, and disinfectants for its emulsifying, antistatic, and antimicrobial properties. In research laboratories it is also used as a template or structure-directing agent in the synthesis of mesoporous silica materials and as a shape-directing agent in the synthesis of nanoparticles. This chemical has a CAS number of 112-02-7, with the molecular formula CH3(CH2)15N(Cl)(CH3)3 and a molecular weight of 320.0. It is typically stored at ambient temperatures and carries a signal word of Danger, indicating hazardous properties. Molekula supplies hexadecyltrimethylammonium chloride from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
