APPLICATIONS

N-Bromosuccinimide is used as a oxidation and brominating agent for organic synthesis especially for pharmaceuticals and hormones. It is also used as an extraction solvent for rare elements. (N-Bromo derivatives and ammonium tribromides are main brominating agents). Carbon-carbon double bonds add chlorine and bromine rapidly in liquid phase. Halogen substitution reaction of alkenes should be carried out in the gas phase with halogenating reagents such as N-bromosuccinimide and N-Chlorosuccinimide. halogenations are carried in the liquid phase.
