Bromocholine (bromide)

2-Bromo-N, N, N-trimethylethanaminium bromide is a quaternary ammonium salt consisting of a positively charged 2-bromo-N, N, N-trimethylethylamine cation and a negatively charged bromide anion. This compound is commonly used as a phase transfer catalyst in organic chemical reactions, facilitating the transfer of reactants between immiscible phases. It can also be used as a halogenating agent, for example in the bromination of olefins.
