Tetrafluorohydrazine
Tetrafluorohydrazine or dinitrogen tetrafluoride,, is a colourless, reactive inorganic gas. It is a fluorinated analog of hydrazine. It is a highly hazardous chemical that explodes in the presence of organic materials.
Tetrafluorohydrazine is manufactured from nitrogen trifluoride using an iron catalyst or iron fluoride. It is used in some chemical syntheses, as a precursor or a catalyst.
Tetrafluorohydrazine was considered for use as a high-energy liquid oxidizer in some never-flown rocket fuel formulas in 1959.
