• in gold nanorods preparation
• as an additive in Ugi reaction
• as a surfactant
• for homogenisation of intestinal tissues for myeloperoxidase activity

생화학적/생리학적 작용

Hexadecyltrimethylammonium bromide also called cetyltrimethylammonium bromide (CTAB), is a cationic surfactant. CTAB is employed for extraction of DNA. CTAB method is efficient, cost and time effective for DNA extraction. CTAB is used as a shaping material and reducing agent for nanoparticle generation.
