Iodine trichloride, which exists in the solid state as the planar dimer I 2 Cl 6, is a bright yellow solid, synthesised by reacting iodine with liquid chlorine at −80 °C; caution is necessary during purification because it easily dissociates to iodine monochloride and chlorine and hence can act as a strong chlorinating agent.
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 ...

Organoiodine chemistry is the study of the synthesis and properties of organoiodine compounds, or organoiodides, organic compounds that contain one or more carbon–iodine bonds. They occur widely in organic chemistry, but are relatively rare in nature.
In iodane chemistry, carbon is considered more electronegative than iodine, despite the Pauling electronegativities of those respective atoms. [2] Thus iodobenzene (C 6 H 5 I) is an iodine(I) compound, (dichloroiodo)benzene (C 6 H 5 ICl 2) and iodosobenzene (C 6 H 5 IO) iodine(III) compounds, and iodoxybenzene (C 6 H 5 IO 2) an iodine(V) compound.
Periodic acid (/ ˌ p ɜːr aɪ ˈ ɒ d ɪ k / per-eye-OD-ik) is the highest oxoacid of iodine, in which the iodine exists in oxidation state +7. It can exist in two forms: orthoperiodic acid, with the chemical formula H 5 IO 6, and metaperiodic acid, which has the formula HIO 4.
The role of iodine in mammary tissue is related to fetal and neonatal development, but its role in the other tissues is not well known. [8] It has been shown to act as an antioxidant [8] and antiproliferant [9] in various tissues that can uptake iodine. Molecular iodine (I 2) has been shown to have a suppressive effect on benign and cancerous ...
Tincture of iodine: iodine in ethanol, or iodine and sodium iodide in a mixture of ethanol and water. Lugol's iodine: iodine and iodide in water alone, forming mostly triiodide. Unlike tincture of iodine, Lugol's iodine has a minimised amount of the free iodine (I 2) component. Iodine glycerin, a preparation used in dentistry.
