The compound known as Freon 12 is dichlorodifluoromethane (CCl₂F₂). It is also referred to as CFC-12.123

Freon 12 belongs to a group of chlorofluorocarbons (CFCs) that were widely introduced in the 1930s as stable, nontoxic, and nonflammable refrigerants. However, these compounds were later found to contribute to the depletion of the ozone layer when they reach the stratosphere and undergo photochemical dissociation. Due to these environmental risks, the production and use of such substances have been largely phased out under international agreements like the Montreal Protocol.13
