Dichlorodifluoroethane (also known as 1,1-dichloro-1,2-difluoroethane or R-132) is a hydrochlorofluorocarbon with the chemical formula C2H3F2Cl2). It is a volatile derivative ethane. It appears as a colourless, odorless non-flammable liquid.[2] The use of Dichlorodifluoroethane is restricted by the US EPA through the Clean Air Act Amendments of 1990 which intend to phase-out the use of substances that deplete the ozone layer, HCFC-132 is cited as an ozone depleting substance, it is considered as a class II substance by the EPA.[3]
