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.
