N-bromo-isobutyramide, also known as N-bromosuccinimide (NBS), is a chemical compound with the formula C4H6BrNO2. It is a pale yellow crystalline solid that is widely used as a brominating agent in organic synthesis. NBS is particularly effective in the bromination of alkenes, leading to the formation of vicinal dibromides, and in the bromination of aromatic compounds. It is also used for the detection of double bonds in organic molecules and for the preparation of other brominated compounds. NBS is a powerful brominating agent and should be handled with care due to its reactivity and potential hazards.
