N-Bromosuccinimide (NBS) is widely used in organic synthesis for selective bromination reactions. It is particularly effective for brominating allylic and benzylic positions in alkenes and aromatic compounds, making it a valuable reagent in the production of pharmaceuticals, agrochemicals, and fine chemicals. NBS is also employed in the Wohl-Ziegler reaction to introduce bromine atoms into organic molecules under mild conditions. Additionally, it serves as a key reagent in the synthesis of bromohydrins from alkenes, which are intermediates in the production of various industrial compounds. In polymer chemistry, NBS is used to modify polymers by introducing bromine groups, enhancing their flame-retardant properties. Its versatility and selectivity make it a crucial tool in both academic research and industrial applications.
