Iodomethane, also called methyl iodide, and commonly abbreviated "MeI", is the chemical compound with the formula CH 3 I. It is a dense, colorless, volatile liquid. In terms of chemical structure, it is related to methane by replacement of one hydrogen atom by an atom of iodine. It is naturally emitted in small amounts by rice plantations. [5]
As a "carcinogen, neurotoxin, and endocrine disruptor" [29] [30] the adverse health effects of methyl iodide on farmworkers and others in the vicinity of its use turned out to be if anything worse than methyl bromide's, and its manufacturer withdrew it from the US market ahead of a decision in litigation brought by Earthjustice.
The potential for methyl iodide to replace the ubiquitous dependence on methyl bromide as a soil fumigant has been considered, however limited information is available on environmental behavior of the former. [5] Ioxynil (3,5-diiodo-4-hydroxybenzonitrile), which inhibits photosynthesis at photosystem II, is among the very few organoiodine ...

Diiodomethane or methylene iodide, commonly abbreviated "MI", is an organoiodine compound. Diiodomethane is a very dense colorless liquid; however, it decomposes upon exposure to light liberating iodine, which colours samples brownish. It is slightly soluble in water, but soluble in organic solvents.
Marine biota uptake iodine from seawater [1] where it may be volatilized by transformation to methyl iodide. [3] Sea spray aerosolization, volcanic activity, and fossil fuel burning cycles iodine from the hydrosphere and lithosphere into the atmosphere as well, [ 1 ] while wet [ 2 ] and dry deposition remove iodine from the atmosphere.

In organic chemistry, a methiodide is a chemical derivative produced by the reaction of a compound with methyl iodide. Methiodides are often formed through the methylation of tertiary amines : R 3 N + CH 3 I → (CH 3 )R 3 N + I −
Trimethylsulfoxonium iodide is a sulfoxonium salt. It is used to generate dimethyloxosulfonium methylide by reaction with sodium hydride . [ 1 ] The latter compound is used as a methylene-transfer reagent, and is used to prepare epoxides .
