Bromodichloromethane is a chemical compound from the group of aliphatic, saturated halogenated hydrocarbons (more precisely trihalomethanes ).

Occurrence

Bromodichloromethane occurs as a by-product of the chlorination of water. Bromodichloromethane is not used industrially.

Properties and use

When bromodichloromethane is heated in the presence of oxygen or reducing agents and metals as a catalyst , it slowly decomposes with the formation of acidic gases (HCl, HBr). This reaction can be used to produce long-life halogen lamps .

safety instructions

Bromodichloromethane is classified as carcinogen category 2 and germ cell mutagen category 3B.
