Application

Hexadecyltrimethylammonium bromide has been used:
  • in gold nanorods preparation
  • as an additive in Ugi reaction
  • as a surfactant
  • for homogenisation of intestinal tissues for myeloperoxidase activity

Biochem/physiol Actions

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.
