Bromine monoxide radical

Bromine monoxide is a binary inorganic compound of bromine and oxygen with the chemical formula BrO.[1][2] A free radical, this compound is the simplest of many bromine oxides. The compound is capable of influencing atmospheric chemical processes.[3] Naturally, BrO can be found in volcanic plumes.[4][5] BrO is similar to the oxygen monofluoride, chlorine monoxide and iodine monoxide radicals.

The compound is very effective as a catalyst of the ozone destruction. The chemical reaction of BrO and chlorine dioxide (OClO) results in ozone depletion in the stratosphere.[6]
