1,1-Dichloro-1,2-difluoroethane (also known as HCFC-132c or R-132c) is a hydrochlorofluorocarbon. It is a volatile derivative of ethane. It appears as a colourless, odorless non-flammable liquid.[2] The use of HCFC-132c 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-132c is cited as an ozone depleting substance; it is considered as a class II substance by the EPA.[3]
