Tetrabutyl Ammonium Bromide
TBAB — the benchmark quaternary ammonium phase transfer catalyst for biphasic organic transformations.
Tetrabutyl ammonium bromide (TBAB) is among the most widely used and versatile phase transfer catalysts in commercial and laboratory organic synthesis. Its lipophilic tetrabutyl chains enable rapid migration of anions across aqueous-organic interfaces, accelerating alkylations, oxidations, reductions, nucleophilic substitutions and Heck reactions. It also serves as a molten salt ionic liquid medium. Assay, moisture limit and packaging are confirmed against enquiry.
