Tetraphenylphosphonium Bromide (TTB) (CAS: 2751-90-8) is a phase transfer catalyst. The application is a new technology developed in the past two decades. It overcomes the shortcomings of the need for polar aprotic solvents in heterogeneous organic synthesis, and can make the heterogeneous reaction proceed under relatively mild conditions, speed up the reaction rate and increase the yield, therefore, it has greatly promoted the development of organic synthesis. Supporting electrode for the electrolytic reduction of Buckminster fullerene. Tetraphenylphosphonium Bromide is mainly used in pharmaceuticals.
