Ethyl 3-bromopropionate is the organobromine compound with the formula BrCH₂CH₂CO₂C₂H₅. It is a colorless liquid and an alkylating agent. It is prepared by the esterification of 3-bromopropionic acid.^[1] Alternatively, it can be prepared by hydrobromination of ethyl acrylate, a reaction that proceeds in an anti-Markovnikov sense.^[2]
