Products Description of Tetraethylammonium Bromide CAS#71-91-0

Tetraethylammonium Bromide (CAS#71-91-0) appears as colorless to white crystals or crystalline powder. The crystals are prismatic or acicular, while the powder is fine, uniform and glossy. It is stable at room temperature with low hygroscopicity, but may slightly agglomerate when exposed to humid environment for a long time. The color remains predominantly white, and may show a slight pale yellow tint if impurities are present.

Product Application of Tetraethylammonium Bromide CAS#71-91-0

Tetraethylammonium bromide (TEAB) catalyzes the synthesis of thioesters by the oxidative coupling of aldehydes or alcohols with thiols or disulfides.

It is used as a catalyst, along with o-iodoxybenzoic acid (IBX), in the oxidation of sulfides to sulfoxides and primary carboxamides to one-carbon dehomologated nitriles.

TEAB can also be used as an organic template to synthesize zeolite beta.
