Abstract: A method for purifying crude rocuronium bromide includes removing the residual solvent in crude rocuronium bromide by vacuum microwave drying or fluidized drying to meet medicinal requirements. High-quality rocuronium bromide can be obtained by the method of the present application. The method makes the large-scale industrial production of rocuronium bromide easy to realize, and can also avoid or reduce the use of diethyl ether which is a flammable and explosive solvent. In addition, the equipment used requires less expense and occupies less space.
