General Description

1-Chloro-1,1,2,2-tetrafluoropropane, also known as norflurane, is a colorless, odorless, and nonflammable organic compound with the chemical formula C3H2ClF4. It is commonly used as a refrigerant and a propellant in aerosol sprays. This chemical is a halogenated hydrocarbon and belongs to the family of hydrochlorofluorocarbons, which are known for their low toxicity and ozone-depleting potential. 1-Chloro-1,1,2,2-tetrafluoropropane has a relatively low global warming potential, making it an environmentally friendly alternative to other fluorocarbon compounds. However, it is still important to handle this chemical with care as it can be harmful if inhaled or ingested and can cause irritation to the skin and eyes.
