Benzyltriethylammonium bromide（Cat No.:L047142）is a quaternary ammonium salt commonly used as a phase-transfer catalyst in organic synthesis. It facilitates the migration of reactants between immiscible phases, such as aqueous and organic layers, enhancing reaction rates and yields. With a benzyl group and three ethyl groups bonded to the nitrogen atom, this compound is highly effective in reactions like alkylations, nucleophilic substitutions, and oxidations. Its solid, crystalline form is easy to handle, and it is soluble in water and polar organic solvents. Benzyltriethylammonium bromide is valued for its stability, efficiency, and broad applicability.
