Sign in to saveAlso known as Difluorodibromomethane, Freon 12B2, Halon 1202, Halon-1202
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).
