Bromomethyl ethyl ketone

Bromomethyl ethyl ketone is a brominated ketone with lachrymatory effects. It was used as a chemical warfare agent in World War I. Bromomethyl ethyl ketone was developed as an alternative to bromoacetone, because acetone, the precursor to bromoacetone, was required for explosives production.^[1][2]
