    Bromination is a normal reaction of organic synthesis. The most used  brominating agent is mixing liquid bromide,chloroform,carbon tetrachloride, dimethyl sulfoxide or acetic acid and water up. However, bromine is a kind of toxic liquid which has the characteristic  volatile, and it usually causes some unnecessary substitution and oxidation reaction in organic synthesis. It ?? s been a long time that chemists have been researching solid bromide to substitute for liquid bromine. In recent years, people have found that  tribromides of organic quaternary ammonium salts, such as pyridinium tribromide, phenyl trimethyl ammonium bromide, tetramethyl ammonium tribromide, benzyl trimethyl ammonium bromide and benzyl triethyl ammonium bromide, which could  be used as solid bromides with different properties for organic synthesis.
    Pyridinium tribromide, which also can be named Pyridine hydrobromide perbromide. This product often can be used as a kind of excellent brominating agent in organic synthesis, and it has a lot of advantages, such as mild reaction conditions, high yield, less side reactions, easy measurement, easy operation and use. By the way, it also could as the intermediate object of Gestrinone.
    Pyridinium tribromide produced by Nanjing Shunxiang has the characteristics of high quality, good stability, safe packaging and suitable price and so on. Abundant production and transformation experience makes the Pyridinium tribromide of Shunxiang earn much trusts and good comment  from domestic and foreign customers.
