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.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
