Aplicaciones

Tetraethylammonium bromide is used as a phase transfer catalyst. It acts as a source of tetraethylammonium ions in pharmacological and physiological studies. It is also employed in organic chemical synthesis. It plays a major role in the preparation of tetraethylammonium superoxide from potassium superoxide for the conversion of primary alkyl halides to dialkyl peroxides. Furthermore, It is utilized as a catalyst in the oxidation of organic sulfide to sulfoxide using o-iodoxybenzoic acid.

Notas

Hygroscopic. Incompatible with strong oxidizing agents and bases.
