N-Bromosuccinimide(Cas 128-08-5) Usage

Description	N-Bromosuccinimide is preferred over molecular bromine (Br2) due to its ease of handling and controlled release of bromine radicals. Anthracene, for instance, can be selectively brominated at position 9 using NBS in a radical process, highlighting its utility in achieving specific modifications in complex organic molecules.
Chemical Properties	white to light yellow crystalline powder
Uses	N-Bromosuccinimide (NBS) is an organic compound widely utilized as a brominating agent in various organic synthesis reactions. It is a convenient source of bromine radicals, making it valuable in radical bromination and electrophilic addition reactions. NBS is characterized by its high reactivity and structural features that facilitate the cleavage of Br⁺ ions.

Incompatibilities between N-Bromosuccinimide and Solvents

Sumio Shimizu*, Yoshiaki Imamura, and Tatsuo Ueki

, Org. Process Res. Dev. 2014, 18, 2, 354–358

Incompatibilities between N-bromosuccinimide (NBS) and solvents were examined by measuring the heat of reaction by an advanced reactive system screening tool (ARSST) and a reaction calorimeter (RC1e). The ARSST experiments showed that amides, THF, and toluene solutions require consideration of incompatibilities with NBS. Isothermal analyses by RC1e revealed accurate heats of incompatibilities and the autocatalytic behaviors of the incompatibilities.
