Vinyl bromide is the organobromine compound with the formula CH2=CHBr. Classified as a vinyl halide, it is a colorless gas at room temperature. It is used as a reagent and a comonomer.
It is produced from ethylene dibromide:
CH2=CHBr is mainly consumted as a comonomer to confer fire retardant properties to acrylate polymers. [2]
Vinyl bromide reacts with magnesium to give the corresponding Grignard reagent CH2=CHMgBr. [3] [4]
Vinyl bromide is listed in List of IARC Group 2A carcinogens as a suspected human carcinogen.
