Phase-transfer catalysis
Moves anions into the organic phase so two-phase reactions run faster and milder.
Tetrabutylammonium bromide (TBAB) is a quaternary ammonium salt used as a phase-transfer catalyst, as an ion-pair reagent and as an intermediate in pharmaceutical and organic synthesis. SUNCHEM supplies TBAB with a batch COA on every shipment.
TBAB carries anions from a water phase into an organic phase, so it speeds up alkylations, substitutions, oxidations and other two-phase reactions under mild conditions — the classic phase-transfer catalyst in pharmaceutical and agrochemical synthesis. It is also used as an ion-pair reagent in chromatography, as an electrolyte, and as an intermediate for other tetrabutylammonium salts.
The product listed on this page as “TABA” with CAS 1643-19-2 and formula C₁₆H₃₆BrN is tetrabutylammonium bromide (TBAB).
Moves anions into the organic phase so two-phase reactions run faster and milder.
Used as an ion-pair reagent in chromatography and as a supporting electrolyte.
We quote against your assay, water and appearance and send the batch COA for each lot.
