2-Bromobutyric acid is an carboxylic acid with the molecular formula C4H7BrO2. It is a clear, yellow liquid. The 2-position is an asymmetric carbon, so there are two enantiomers of this compound. 2-Bromobutyric acid is mainly used as a building block chemical, such as in the preparation of Levetiracetam,[citation needed] an anticonvulsant medication.[1]
Production
2-Bromobuyric acid may be prepared by the acid-catalyzed Hell–Volhard–Zelinsky reaction, where butyric acid is treated with elemental bromine.
