N-Bromosuccinimide Usage And Synthesis
Chemical Properties white to light yellow crystalline powder
Uses N-Bromosuccinimide is a brominated succinimide used as a chemical reagent in radical substitution and electrophilic addition reactions in organic synthesis.
Uses NBS, is a chemical reagent used in organic chemistry in electrophilic addition reactions and radical substitution
Uses In bromination of olefins; in oxidation of alcohols to aldehydes and ketones and of aldehydes to acid bromides.
Definition 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.
