N-Bromosuccinimide (NBS), CAS 128-08-5, is the most popular mild selective brominating reagent in organic chemistry. Our offered NBS features 99% purity, low impurity content, stable storage performance and controllable bromination effect for Wohl-Ziegler allylic & benzylic bromination.

It is widely adopted in pharmaceutical API & intermediate synthesis, pesticide production, rubber auxiliary manufacturing and laboratory research. Different from liquid bromine, NBS performs gentle and selective radical substitution, protecting sensitive functional groups and lowering over-bromination risk.

We maintain stable inventory for lab-scale and industrial bulk orders. Pre-shipment COA is available, and we can arrange sample delivery for your reaction verification.
