Tetraethylammonium bromide 71-91-0 Application:
It has been used as the source of tetraethylammonium ions in pharmacological and physiological studies, but is also used in organic chemical synthesis.
Tetraethylammonium bromide 71-91-0 Synthesis: Tetraethylammonium bromide is commercially available, but can be prepared by the reaction between tetraethylammonium hydroxide and hydrobromic acid:
Et4N+HO− + HBr → Et4N+Br− + H2O
Evaporation of the water and recrystallization from acetonitrile yields a crystalline sample of Tetraethylammonium bromide.
