Povidone-iodine after treatment with radioiodine, and in patients with dermatitis herpetiformis (Duhring's disease). The sensitization rate to the product is 0.7%. The iodine in PVP-I reacts with hydrogen peroxide, silver, taurolidine and proteins such as enzymes, rendering them (and itself) ineffective. It also reacts with many mercury compounds, giving the corrosive compound mercury iodide, as well as with many metals, making it unsuitable for disinfecting metal piercings. Iodine is absorbed into the body to various degrees, depending on application area and condition of the skin. As such, it interacts with diagnostic tests of the thyroid gland such as radioiodine diagnostics, as
Iodine pentafluoride forming nitriles after hydrolysis with water: Iodine pentafluoride is available as a "Special Gas" for flooding into the atmosphere of the escape shuttle in the terminal sequence of 1979 film Alien. Iodine pentafluoride Iodine pentafluoride is an interhalogen compound with chemical formula IF. It is a fluoride of iodine. It is a colorless or yellow liquid with a density of 3.250 g cm. It was first synthesized by Henri Moissan in 1891 by burning solid iodine in fluorine gas. This exothermic reaction is still used to produce iodine pentafluoride, although the reaction conditions have been improved. Iodine pentafluoride is a
