N-Bromosuccinimide Characteristic:
N-Bromosuccinimide, commonly abbreviated NBS, white to milky white fine crystals.
N-Bromosuccinimide:Soluble in acetone, tetrahydrofuran, N,N-dimethylformamide, dimethyl sulfoxide and acetonitrile, slightly soluble in water and acetic acid, insoluble in ether, hexane and carbon tetrachloride. N-Bromosuccinimide/NBS is commonly used in the bromination of free radicals of allyl and benzyl groups; electrophilic bromination of ketones, aromatic compounds or heterocyclic compounds; hydroxylation of alkenes, ether-forming reactions and lactonization reactions.
N-Bromosuccinimide/NBS is sensitive to moisture and should be kept in the refrigerator. During use, avoid inhalation or sticking to the skin, generally operate in a well-ventilated fume hood.
