Perchloryl fluoride is a reactive gas. It has a characteristic sweet odor that resembles gasoline and kerosene. It is toxic and is a powerful oxidizing and fluorinating agent. It is the acid fluoride of perchloric acid. Perchloryl fluoride 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. It 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. It can also be used in flame photometry as an excitation source.
