Fluomine

Fluomine is a chemical compound containing a cobalt chelate. It has the ability to form a complex with molecular oxygen (O2) and then release it upon heating. Because of this ability to reversibly sorb and desorb oxygen, it has been used in high-altitude aircraft oxygen-generating systems.

The toxicity of fluomine has been studied and it is classified by the Emergency Planning and Community Right-to-Know Act as an extremely hazardous substance.
