<unk>  is used in organic chemistry as a mild fluorinating agent. It was the first industrially relevant electrophilic fluorinating agent, used since the 1960s for producing fluorinated steroids. In the presence of aluminum trichloride, it has also been used as an electrophilic<unk> ation reagent for aromatic compounds.<unk>  was investigated as a high performance liquid rocket fuel oxidizer. In comparison with chlorine pentafluoride and bromine pentafluoride, it has significantly lower specific impulse, but does not tend to corrode tanks. It does not require cryogenic storage. Rocket fuel chemist John Drury Clark reported in his book Ignition! that<unk>  is completely miscible with all-halogen oxidizers such as chlorine trifluoride and chlorine pentafluoride, and such a mixture provides the needed oxygen to properly burn carbon-containing fuels. It can also be used in flame photometry as an excitation source.
