Physical Description
Oxygen difluoride appears as a colorless poisonous gas with a strong peculiar odor. Highly toxic by inhalation. Corrosive to skin and eyes. Can explode on contact with water. Decomposes to toxic gaseous fluorine if heated to high temperature. Prolonged exposure of the containers to high heat may result in their violent rupturing and rocketing. Used as an oxidizer for propellants.

Biological Half Life
... Bone retains about 60% of iv-injected fluoride and that the half-time for this uptake is only about 13 min; both blood and extracellular fluid levels therefore decr rapidly. After ingestion of sodium fluoride, plasma fluoride levels show a much slower change with a half-life of about 3 hr ... . /Fluorides/
