What is Decyltrimethylammonium bromide?
Chemical properties
white to beige chunks and powder
The Uses of Decyltrimethylammonium bromide
(1-Decyl)trimethylammonium bromide is used in high performance liquid chromatography and in nuclear magnetic resonance. It is an important raw material and intermediate used in organic synthesis, pharmaceuticals and agrochemicals.
Definition
ChEBI: A quarternary ammonium salt whose basic unit comprises a decyltrimethylammonium cation and a bromide anion.
Purification Methods
Crystallise the salt from 50% (v/v) EtOH/Et2O, or from acetone and wash with ether. Dry it under vacuum at 60o. Also recrystallise it from EtOH and dry it over silica gel. [McDonnell & Kraus J Am Chem Soc 73 2170 1952, Dearden & Wooley J Phys Chem 91 2404 1987, Beilstein 4 IV 784.]
