Dodecyltrimethylammonium Bromide Usage And Synthesis

Chemical Propertieswhite to slightly yellow powder
UsesDodecyltrimethylammonium Bromide is a quaternary ammonium salt useful as paint strippers, foaming stabilizers, and bactericidal lotions.
DefinitionChEBI: A quarternary ammonium cation having one dodecyl and three methyl substituents around the central nitrogen.
Purification MethodsPurify the salt by repeated crystallisation from acetone. Wash it with diethyl ether and dry it in a vacuum oven at 60o [Dearden & Wooley J Phys Chem 91 2404 1987]. [Beilstein 4 IV 798.]
