'''1,1,1-Trifluoroethane''', or '''R-143a''' or simply '''trifluoroethane''', is a ] (HFC) compound that is a colorless gas. It should not be confused with the much more commonly used HFC gas ], nor confused with the ]ic compound 1,1,2-trifluoroethane. 1,1,1-Trifluoroethane has a ] of 73 °C.<ref name=Schoen>{{Citation|last=Schoen |first=J.

Unlike ] used as refrigerants, trifluoroethane has no chlorine atoms and therefore is not ].
