Phenacyl bromide is the organic compound with the formula C6H5C(O)CH2Br. This colourless solid is a powerful lachrymator as well as a useful precursor to other organic compounds.

It is prepared by bromination of acetophenone:[2]

C6H5C(O)CH3 + Br2 → C6H5C(O)CH2Br + HBr

The compound was first reported in 1871.[3]
