Hexafluorobenzene is used as a solvent in photochemical reactions. It is also used as a reference compound in fluorine-19 NMR, carbon-13 NMR. It is used as a solvent in proton NMR, IR spectrum and UV-spectra. It is used as anticorrosive, antifriction and anti-tumor agents. Further, it is used as a reference molecule to investigate tissue oxygenation in vivo studies. It forms series of 1:1 complexes with naphthalene, anthracene, phenanthrene, pyrene and triphenylene.
