Product Description

Property

CAS No.: 420-46-2 Formula: C2H3F3 Molecular Weight: 84.04040

Description

1,1,1-Trifluoroethane, or R-143a or simply trifluoroethane, is a hydrofluorocarbon compound that is a clear, colorless gas. It should not be confused with the much more commonly used gas R-134a or the isomeric compound 1,1,2-trifluoroethane.
It has a critical temperature of 73 °C.
It is used as a refrigerant either by itself or more commonly as a component of blended mixtures. Unlike CFCs used as refrigerants, trifluoroethane 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 with a global warming potential of 4300, higher than many other commonly used HFC refrigerants.
Trifluoroethane is also used as a propellant in canned air products used to clean electronic equipment.
