Hexadecyl trimethyl ammonium bromide Chemical Properties,Usage,Production

Chemical Properties

White powder. Soluble in water, alcohol, and chloroform.

Uses

Hexadecyltrimethylammonium Bromide (CTAB) is a cationic surfactant used as a template in the synthesis of Mesoporous γ-Fe2O3.

Uses

cetrimonium bromide is a quaternary ammonium salt that can prevent the proliferation of bacteria, fungi, and yeast in cosmetic preparation, while also act as an emulsifying agent.

Uses

antiinfectant

Uses

A cationic detergent used in the isolation of high molecular weight DNA.

Definition

ChEBI: The organic bromide salt that is the bromide salt of cetyltrimethylammonium; one of the components of the topical antiseptic cetrimide.

General Description

Hexadecyltrimethylammonium bromide is a titrant for the potentiometric titration of perchlorate with ionselective electrodes.

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.

Purification Methods

Crystallise it from EtOH, EtOH/*benzene or from wet acetone after extracting twice with pet ether. Shake it with anhydrous diethyl ether, filter and dissolve it in a little hot MeOH. After cooling in the refrigerator, the precipitate is filtered off at room temperature and re-dissolved in MeOH. Anhydrous ether is added and, after warming to obtain a clear solution, it is cooled and the crystalline material is collected. [Dearden & Wooley J Phys Chem 91 2404 1987, Hakemi et al. J Am Chem Soc 91 120 1987, Beilstein 4 IV 819.]
