| Hexadecyl trimethyl ammonium bromide Usage And Synthesis |
| Chemical Properties |
White powder. Soluble in water, alcohol, and chloroform. |
| Uses |
antiinfectant |
| Uses |
Hexadecyltrimethylammonium Bromide (CTAB) is a cationic surfactant used as a template in the synthesis of Mesoporous γ-Fe2O3. |
| Uses |
A cationic detergent used in the isolation of high molecular weight DNA. |
| 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. |
| Definition |
ChEBI: The organic bromide salt that is the bromide salt of cetyltrimethylammonium; one of the components of the topical antiseptic cetrimide. |
| Purification Methods |
Crystallise it from EtOH, EtOH/*benzene or from wet after extracting twice with pet r. Shake it with anhydrous diethyl r, 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 r 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.
