| Octadecy trimethyl ammonium bromide Usage And Synthesis |
| Chemical Properties | white powder |
| Uses | Trimethyloctadecylammonium bromide (C18TAB) is generally used as a surfactant. It can be used in the preparation of polyoxomolybdate-surfactant hybrid layered crystals. It can also be used as a surface modifier in the liquid chromatography. |
| Uses | A Dynamin I inhibitor. |
| Flammability and Explosibility | Notclassified |
| Purification Methods | Crystallise it from EtOH or H2O (solubility is 1 in 1000parts). It is very soluble in Me2CO. It is a bactericide. [Sheldon et al. J Am Chem Soc 68 754 1946, Grieger & Kraus J Am Chem Soc 70 3805, 38007, Beilstein 4 IV 827.] |
