Vinyl bromide is a simple vinyl halide. It is a colorless liquid. It is produced from ethylene dibromide. It is mainly used as a comonomer to confer fire retardant properties to acrylate polymers.[2]

Reactions and applications

It reacts with magnesium to give the corresponding Grignard reagent.[3][4]

Safety precautions

Vinyl bromide is listed in List of IARC Group 2A carcinogens as a suspected human carcinogen.
