Infobox disclaimer and references

1,1,1-Trifluoroethane, or R-143a or simply trifluoroethane, is a fluorocarbon compound that is a clear, colorless gas. It should not be confused with 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 a potent ozone-depleting chemical.

Trifluoroethane is also used as a propellant in canned air products used to clean electronic equipment.
