Norflurane (1,1,1,2-Tetrafluoroethane) is a non-flammable gas used primarily as a "high-temperature" refrigerant for domestic refrigeration and automobile air conditioners. Other uses include plastic foam blowing, as a cleaning solvent, a propellant for the delivery of pharmaceuticals (e.g. bronchodilators), wine cork removers, gas dusters, and in air driers for removing the moisture from compressed air. Liquid Norflurane absorbs a high amount of thermal energy from the environment during its evaporation at atmospheric pressure. Norflurane is commercially available as a liquid in pressurized cylinders or cans. Norflurane is used as a propellant for some metered dose inhalers and as an inhalational anesthetic agent in animal studies.
