2-Chloro-1,1,1,2-tetrafluoroethane

Gas; odorless; colorless. Much heavier than air. Nonflammable.

HCFC 124 has recently been developed as a replacement for fully halogenated chlorofluorocarbons. Its primary applications are as a refrigerant and foam-blowing agent.

Colorless nonflammable gas. Nearly odorless.

2-Chloro-1,1,1,2-tetrafluoroethane is chemically inert in many situations, but can react violently with strong reducing agents such as the very active metals and the active metals. They suffer oxidation with strong oxidizing agents and under extremes of temperature.
