CTAB (Cetyltrimethylammonium Bromide) 500 GR – AFG Scientific

Cetyltrimethylammonium Bromide (CTAB) is a cationic surfactant commonly employed in molecular biology and nanomaterial research laboratories. Supplied by AFG Scientific at ≥99% purity, this 500 gr package is preferred in DNA/RNA extraction protocols for cell lysis and polysaccharide removal, as well as serving as a template agent in nanoparticle synthesis (particularly in gold nanorod fabrication).

This white crystalline powder form is stable at room temperature and possesses an extended shelf life due to its high melting point (>230°C, decomposition). Identified by CAS number 57-09-0, this compound is also known as Cetrimonium bromide and Hexadecyltrimethylammonium bromide.

With a molecular formula of C19H42NBr and molecular weight of 364.46 g/mol, CTAB serves as a reliable raw material source for both research and routine laboratory applications.
