For most applications, the agent must be highly soluble in water and, of course, non-toxic and readily excreted.
Iodine forms all three possible diatomic interhalogens, a trifluoride and trichloride, as well as a pentafluoride and, exceptionally among the halogens, a heptafluoride. Numerous cationic and anionic derivatives are also characterised, such as the wine-red or bright orange compounds of ICl + 2 and the dark brown or purplish black compounds of I ...
