Quaternary ammonium salts
AdipoGen Tetrabutylammonium tribromide
Chemical. CAS 38932-80-8. Formula C16H36Br3N. MW 482.18. Tetrabutylammonium tribromide TBABr3 is used as a reagent in organic synthesis, particularly in organic and organometallic chemistry. It is a quaternary ammonium salt and is composed of a tetrabutylammonium cation C16H36N and three bromide anions Br-. TBABr3 is a powerful brominating agent, to introduce bromine Br atoms into organic molecules, and it is particularly useful for bromination reactions in cases where other brominating agents might not be suitable or effective. The tetrabutylammonium cation in TBABr3 serves as a phase-transfer catalyst, facilitating the transfer of the bromide ions into the organic phase of a reaction. This allows for the selective bromination of various organic substrates. TBABr3 is used in a variety of organic reactions, including the preparation of intermediates for pharmaceuticals, and in other applications where the introduction of bromine is required.
