Product Description

N-Bromosuccinimide organic reagent CAS 128-08-5 applied in allylic substitution

Product Introduction

N-Bromosuccinimide, abbreviated as NBS, CAS registry number 128-08-5, belongs to organic brominated reagent. This white to pale yellow crystalline solid carries faint bromine odour. It decomposes under strong light and elevated temperature. The substance dissolves in ethyl acetate while showing limited solubility in water. It acts as controlled source of bromine radical and enables selective bromination under mild reaction conditions.

Application

N-Bromosuccinimide supports selective bromination in organic synthesis. It completes allylic and benzylic bromination following Wohl-Ziegler mechanism. It serves as intermediate raw material for pharmaceutical and agrochemical development. It also works for oxidation and halogen transformation in laboratory research.

Storage

Store in tightly sealed containers. Shield from direct light and heat sources. Keep apart from reducing agents and strong bases. Wear protective gear while handling.
