1,2-Dibromotetrafluoroethane (C 2 Br 2 F 4) is a haloalkane. It is also known under codenames R-114B2 and Halon 2402. It is a colorless liquid with a boiling point of 47.2 °C. R-114B2 is occasionally used in fire suppression systems. It is highly volatile, passes through soil to air, and can be detected in the parts-per-quadrillion range.
Halon 1211 is also a potent greenhouse gas with a 100-year global warming potential 2,070 times that of carbon dioxide and an atmospheric lifetime of 16.0 years. [6] Recycling of Halon 1211 allows it to remain in use, [7] [8] although parts availability is limited to a few manufacturers and can be an issue. Halon 1211 is still widely used in ...
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).

Halon 1301 and 1211 are being replaced with new halocarbon agents which have no ozone depletion properties and low atmospheric lifetimes, but are less effective. Halon 2402 is a liquid agent (dibromotetrafluoroethane) which has had limited use in the West due to its higher toxicity than 1211 or 1301.
