Tetrabutylammonium bromide (TBAB) is a quaternary ammonium salt with a bromide commonly used as a phase transfer catalyst. It is used to prepare many other tetrabutylammonium salts by salt metathesis reactions.

Tetrabutylammonium bromide (TBAB) is a quaternary ammonium compound. It is the most widely used phase transfer catalyst. ... TBAB is reported to decrease retention time and remove peak tailing by acting as an ion pair reagent during the chromatographic analysis of quaternary ammonium compounds.

Tetrabutylammonium bromide (TBAB) is a quaternary ammonium compound. It is the most widely used phase transfer catalyst. Its interfacial properties have been studied in case of hydroxide initiated reactions. This may be applied in understanding the mechanism of phase transfer reactions.

Tetrabutylammonium bromide is prepared buy mixing n-butylbromide with tributylamine in acetonitrile, in an inert atmosphere, under reflux conditions for a sufficient period of time to form a solution containing tetrabutylammonium bromide, cooling the resulting solution; mixing the solution with water, thus forming a
