Dibromodifluoromethane
Encyclopedia
Dibromodifluoromethane is a mixed halomethane
. It is a colorless non-flammable liquid.
Along with Halons 1211, 2402
, and 1301, it is the most effective fire extinguishers, however, also the most toxic one.
It is a class I ozone depleting substance (ODS).
Halomethane
Halomethane compounds are derivatives of methane with one or more of the hydrogen atoms replaced with halogen atoms . Halomethanes are both naturally occurring, especially in marine environments, and man-made, most notably as refrigerants, solvents, propellants, and fumigants...

Dibromotetrafluoroethane
1,2-Dibromotetrafluoroethane 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 also used as a tracer chemical in Praxair's Seep Sense leak detection...
