Dibromodifluoromethane is a mixed halomethane. It is a colorless non-flammable liquid. Along with Halons 1211, 2402, and 1301, it is one of the most effective fire extinguishers, however, it is also very toxic. It is a class I ozone depleting substance (ODS).
A known use for dibromodifluoromethane is in the synthesis of halfenprox. Synthesis Dibromodifluoromethane can be obtained by vapor phase bromination of difluoromethane.
It is also formed during the fluorination of carbon tetrabromide.
