• Bromine pentafluoride was first prepared in 1931 by the direct reaction of bromine with fluorine.
• "' Bromine pentafluoride "', interhalogen compound and a fluoride of bromine.
• In comparison with chlorine pentafluoride and bromine pentafluoride, it has significantly lower specific impulse, but does not tend to corrode tanks.
• The pale-brown bromine monofluoride ( BrF ) is unstable at room temperature, disproportionating quickly and irreversibly into bromine, bromine trifluoride, and bromine pentafluoride.
• Looking at : Category : Sulfates, a number of sulfur-free fluoride compounds from : Category : Fluorides ) have appeared, including magnesium fluoride and bromine pentafluoride among others.
