It is a colorless gas under ordinary temperature with slight fragrance, and a colorless & transparent liquid under the pressure of itself, easily soluble in oil but poorly in water. It is mainly used in the refrigerating systems under high temperature conditions, thermostatic control switches, the intermediate of aerial propellant, and the important raw material for vinylidene fluoride.
