Quaternary ammonium salt
Tetrabutylammonium Bromide (CAS 1643-19-2), also known as TBAB, is a quaternary ammonium salt widely used as a phase-transfer catalyst (PTC) in organic synthesis. It appears as a white crystalline powder and is highly soluble in water, alcohols, and polar organic solvents. TBAB facilitates the migration of anions from aqueous to organic phases, enabling efficient two-phase reactions.
Acts as a phase-transfer catalyst to enhance reactivity in biphasic systems
Used in nucleophilic substitution, oxidation, alkylation, and polymerization reactions
Essential intermediate and reagent in drug development and API synthesis
Supports green chemistry by reducing the need for harsh solvents
Used as an electrolyte or supporting salt in electrochemical studies
Applied in ionic liquids, surfactants, and ionic conductors
Catalyzes processes in pesticide, plastic, and dye manufacturing
Enhances yield and selectivity in industrial-scale chemical reactions
