N-BromoSuccinimide

Product Description

N-BromoSuccinimide

Preparation

NBS is commercially available. It can also be synthesized in the laboratory. To do so, sodium hydroxide and bromine are added to an ice-water solution of succinimide. The NBS product precipitates out and can be collected by filtration.[citation needed]

Crude NBS gives better yield in the Wohl-Ziegler reaction. In other cases, impure NBS (slightly yellow in color) may give unreliable results. It can be purified by recrystallization from 9095C water (10 g of NBS for 100 mL of water).
