C2 F4 Cl4

C₂F₄Cl₄ is a chlorofluorocarbon (CFC) compound, a synthetic halogenated hydrocarbon historically used as a specialty chemical in industrial processes. Though largely phased out under the Montreal Protocol due to ozone-depletion potential, it remains documented in materials databases for legacy equipment maintenance, historical engineering reference, and specialized low-volume applications where alternatives are technically unsuitable. Its notable properties—including chemical inertness, non-flammability, and low toxicity—made it valuable in precision cleaning, refrigeration, and specialized solvent roles before regulatory restriction.
