Octadecy trimethyl ammonium bromide Usage And Synthesis
Chemical Propertieswhite powder
UsesA Dynamin I inhibitor.
UsesTrimethyloctadecylammonium 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.
Flammability and ExplosibilityNot classified
Purification MethodsCrystallise 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.]
