应用

  • Cyanogen bromide is widely used in protein immobilization and cleavage.
  • Under von Braun reaction conditions, CNBr reacts with tertiary amines to yield respective organocyanamides.
  • It can also be used to synthesize organic intermediates like cyanuric bromide, derivatives of urea, guanidine, creatine, aryl nitriles, and a variety of heterocyclic compounds.
