1,1,1,2-tetrafluoroethane is a colorless gas commonly used as a refrigerant and propellant in aerosol products. It is part of the hydrofluorocarbon (HFC) family, which are compounds that contain hydrogen, fluorine, and carbon. This chemical is known for its low toxicity and effectiveness in heat transfer applications. Due to its ozone-depleting potential, 1,1,1,2-tetrafluoroethane is being phased out in many regions under the Montreal Protocol. It is often replaced by more environmentally friendly alternatives. The compound is also used in the manufacturing of semiconductors and as a solvent in various industrial processes.
