N-Bromosuccinimide Chemical Properties,Uses,Production

Chemical Properties

white to light yellow crystalline powder


N-Bromosuccinimide is a brominated succinimide used as a chemical reagent in radical substitution and electrophilic addition reactions in organic synthesis.


NBS, is a chemical reagent used in organic chemistry in electrophilic addition reactions and radical substitution


In bromination of olefins; in oxidation of alcohols to aldehydes and ketones and of aldehydes to acid bromides.


ChEBI: A five-membered cyclic dicarboximide compound having a bromo substituent on the nitrogen atom.

Safety Profile

Poison by intraperitoneal route. An irritating poison to skin, eyes, and mucous membranes. Reacts explosively with adme, dtallyl sulfide, and hydrazine hydrate. Explosive reaction with propiononitrile after heating to 105℃ for 24 hours. Violent reaction with dtbenzoyl peroxide + 4-tok acid. When heated to decomposition it emits toxic fumes of Brand NOx. See also BROMIDES and NITROGEN MONOXIDE.

Purification Methods

N-Bromosuccinimide (30g) is purified by dissolving rapidly in 300mL of boiling water and filtering through a fluted filter paper into a flask immersed in an ice bath, and left for 2hours. The crystals are filtered off, washed thoroughly with ca 100mL of ice-cold water and drained on a Büchner funnel before drying under vacuun over P2O5 or CaCl2 [Dauben & McCoy J Am Chem Soc 81 4863 1959]. This brominating agent has also been crystallised from acetic acid or water (10 parts), washed in water and dried in vacuo [Wilcox et al. J Am Chem Soc 108 7693 1986, Shell et al. J Am Chem Soc 108 121 1986, Phillips & Cohen J Am Chem Soc 108 2013 1986, Beilstein 21/9 V 543.]
