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. [2]
Perfluoro(2-methyl-3-pentanone) is a fluorinated ketone with the structural formula CF 3 CF 2 C(=O)CF(CF 3) 2, a fully-fluorinated analog of ethyl isopropyl ketone. It is used as an electronics coolant liquid and fire protection fluid sold commercially by 3M under brand names such as Novec 1230 , Novec 649 , and FK-5-1-12 .
1,1,2,2-Tetrafluoroethane (also called R-134 or HFC-134) is a hydrofluorocarbon, a fluorinated alkane. It is an isomer of the more-used 1,1,1,2-tetrafluoroethane (R-134a). It is used as a foam expansion agent and heat transfer fluid.

Perfluoro-1,3-dimethylcyclohexane is chemically inert and thermally stable (to over 400 °C). It is a clear, colorless liquid, with a relatively high density, low viscosity and low surface tension that will rapidly evaporate. It is a relatively good solvent for gases, but a poor solvent for solids and liquids. [2]
