Applications
N-Bromosuccinimide is a chemical reagent used in electrophilic additions and radical substitution reactions in synthetic organic chemistry. In Wohl-Ziegler reaction, it is involved in allylic and benzylic bromination reaction. It is also used in the alfa-bromination of carbonyl derivatives. In the Hofmann rearrangement, it is used in the presence of a strong base, such as 1,8-Diazabicyclo[5.4.0]undec-7-ene (DBU) reacts with primary amides to produce a carbamate. It oxidizes silyl ethers to aldehydes in the presence of azobisisobutyronitrile. It is also used for the modification of ribosomal sulfhydryl groups.

Solubility
Soluble in acetone, tetrahydrofuran, dimethyl formamide, dimethyl sulfoxide and acetonitrile. Slightly soluble in water and acetic acid. Insoluble in ether, hexane and carbon tetrachloride.

Notes
Moisture and light sensitive. Incompatible with strong oxidizing agents, strong acids, strong bases, iron, iron salts, halogenated hydrocarbons, amines and metals. Store in a cool place.
