Dichlorodifluoromethane (R-12), usually sold under the brand name Freon-12, is a chlorofluorocarbon halomethane used as a refrigerant and aerosol spray propellant until its manufacture was discontinued in 1995, due to concerns about damage to the ozone layer. The ozone depletion potential of R-12 is 0.82, which is relatively high.

However, as of 2005, it is still found along with trichloromonofluoromethane in aerosols, for example USP-approved Albuterol.
