Ethane,1,1,1-trifluoro-

The 1,1,1-Trifluoroethane, with the CAS registry number 420-46-2, is also known as Freon 143a. It belongs to the product categories of Refrigerants; Refrigerant. Its EINECS registry number is 206-996-5. This chemical's molecular formula is C₂H₃F₃ and molecular weight is 84.04. What's more, its IUPAC name is same with its product name. It is a fluorocarbon compound that is a clear, colorless gas. It should not be confused with the isomeric compound 1,1,2-trifluoroethane. Unlike CFCs used as refrigerants, it has no chlorine atoms and is therefore not an ozone-depleting chemical, though its high chemical stability and infra-red absorbency make it a potent greenhouse gas.
