Descripción general del producto & beneficios clave
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).
Ion-pair and electrolyte use
Used as an ion-pair reagent in chromatography and as a supporting electrolyte.
