Povidone-iodine in people with thyroid problems. Povidone-iodine is a chemical complex of povidone, hydrogen iodide, and elemental iodine. It contains from 9% to 12% available iodine. It works by releasing iodine which results in the death of a range of microorganisms. Povidone-iodine came into commercial use in 1955. It is on the World Health Organization's List of Essential Medicines, the most effective and safe medicines needed in a health system. Povidone-iodine is available over the counter. The wholesale cost in the developing world is about 3.30 to 11.40 per liter of 10% solution. This amount in the United Kingdom cost the
Iodine monofluoride −45 °C in CClF: It can also be generated by the reaction of iodine with iodine trifluoride at −78 °C in CClF: The reaction of iodine with silver(I) fluoride at 0 °C also yields iodine monofluoride: Iodine monofluoride is used to produce pure nitrogen triiodide: Iodine monofluoride Iodine monofluoride is an interhalogen compound of iodine and fluorine with formula IF. It is a chocolate-brown solid that decomposes at 0 C, disproportionating to elemental iodine and iodine pentafluoride: However, its molecular properties can still be precisely determined by spectroscopy: the iodine-fluorine distance is 190.9 pm and the I−F bond dissociation energy
