Description

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

Packaging

25, 100, 250 g in glass bottle

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.
