Tetraethylammonium bromide CAS#71-91-0

Tetraethylammonium bromide is usually a white crystal or white to milky white crystalline powder, with a certain hygroscopicity and is prone to absorbing moisture in moist air. It is highly soluble in water and the solution is neutral or weakly acidic. In addition, it is readily soluble in ethanol, chloroform and acetone, and slightly soluble in benzene.

Product Usage

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.
