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]
