The IUPAC name of p-Chlorophenacyl bromide is 2-bromo-1-(4-chlorophenyl)ethanone. With the CAS registry number 536-38-9 and EINECS 208-631-5, it is also named as 2-Bromo-4'-chloroacetophenone. The product's categories are Aromatic Acetophenones & Derivatives (substituted); Aromatics Compounds; Aromatics; Acetophenone Series. It is crystalline powder which is lachrymatory, toxic and flammable. When heated to decomposition it emits toxic vapors of Br⁻ and Cl⁻. So the storage environment should be well-ventilated, low-temperature and dry.
