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.
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.

There was a faster phase-out of halon-1211, -2402, -1301, There was a slower phase-out (to zero by 2010) of other substances (halon 1211, 1301, 2402; CFCs 13, 111, 112, etc.) [contradictory] and some chemicals were given individual attention (Carbon tetrachloride; 1,1,1-trichloroethane).
Bromochlorodifluoromethane (BCF), also referred to by the code numbers Halon 1211 and Freon 12B1, is a haloalkane with the chemical formula C F 2 Cl Br. It is used for fire suppression, especially for expensive equipment or items that could be damaged by the residue from other types of extinguishers. [ 1 ]
Haloalkane. Tetrafluoroethane (a haloalkane) is a colorless liquid that boils well below room temperature (as seen here) and can be extracted from common canned air canisters by simply inverting them during use. The haloalkanes (also known as halogenoalkanes or alkyl halides) are alkanes containing one or more halogen substituents. [1]
Halon comparison. FS 49 C2 is believed to cause less damage to the environment. Its main component is the most widely used replacement gas for refrigeration systems, characterized by zero Ozone Depletion Potential (ODP) factor. FS 49 C2 is suitable to replace Halon 1301 as a "drop in" upgrade of existing Halon systems.
In addition to the work on the destruction of aryl chlorides, it has been shown that aliphatic chlorine and bromine compounds such as perchloroethylene, [12] Freon (1,1,2-trichloro-1,2,2-trifluoroethane) and halon-2402 (1,2-dibromo-1,1,2,2-tetrafluoroethane) can be dehalogenated by the action of radiation on alkaline isopropanol solutions ...
