Application
- Cyanogen bromide is widely used in protein immobilization[1][2] and cleavage.[3]
- Under von Braun reaction conditions, CNBr reacts with tertiary amines to yield respective organocyanamides.[4][5]
- 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.[6][7][8][9]
