Description

General description

Tetrabutylammonium bromide, a quaternary ammonium compound widely used as a phase transfer catalyst. TBAB decreases the retention time and removes peak tailing by acting as an ion pair reagent during the chromatographic analysis of quaternary ammonium compounds. In the molten state, TBAB behaves like an ionic liquid, which is a promising green alternative to organic solvents in polymer synthesis.

Application

TBAB may have been used as ion-pairing reagent in phase-transfer catalytic extraction and derivatization procedure during micropollutant determination from water samples using GC technique.
