It is common across all domains of life and uses tyrosine bonded to iodine. [23] Plants, insects, zooplankton and algae store iodine as mono-iodotyrosine (MIT), di-iodotyrosine (DIT), iodocarbons, or iodoproteins. [24] [25] [26] Many plants use thyroid like hormones for regulating growth. [24] [27]
A few organic oxidising agents like the iodanes contain iodine in a higher oxidation state than −1, such as 2-iodoxybenzoic acid, a common reagent for the oxidation of alcohols to aldehydes, [24] and iodobenzene dichloride (PhICl 2), used for the selective chlorination of alkenes and alkynes. [25]
Lugol's iodine is a liquid made up of two parts potassium iodide for every one part elemental iodine in water. [8] Lugol's iodine was first made in 1829 by the French physician Jean Lugol. [7] [8] It is on the World Health Organization's List of Essential Medicines. [9] [10] Lugol's iodine is available as a generic medication and over the ...
Iodine is a micronutrient and dietary mineral that is naturally present in the food supply in some regions, especially near sea coasts but is generally quite rare in the Earth's crust since iodine is a so-called heavy element, and abundance of chemical elements typically declines with greater atomic mass.
Iodine-124 can be made by numerous nuclear reactions via a cyclotron. The most common starting material used is 124 Te. Iodine-124 as the iodide salt can be used to directly image the thyroid using positron emission tomography (PET). [9] Iodine-124 can also be used as a PET radiotracer with a usefully longer half-life compared with fluorine-18 ...
The "2% free iodine" description is based on the quantity of elemental iodine, not sodium/potassium iodide. [citation needed] USP Strong Iodine Tincture is defined in the NF as containing in each 100 mL, 6.8 to 7.5 gram of iodine, and 4.7 to 5.5 gram of potassium iodide. Purified water is 50 mL and the balance is alcohol.
