Perfluorocyclohexane or dodecafluorocyclohexane is a chemical which belongs to the class of fluorocarbons, sometimes referred to as perfluorocarbons or PFCs.

Fluorocarbons and their derivatives are useful fluoropolymers, refrigerants, solvents, and anesthetics.

[2] Perfluorocyclohexane is chemically inert and thermally stable.

It is a relatively non-toxic, clear, waxy solid, which has a high vapor pressure and therefore sublimes readily at room temperature.

[citation needed] The molecule predominantly exists in its chair conformation, in which it possesses D3d molecular symmetry.
