Use
Iodomethane is a useful methylating agent that mediates the alkylation of carbon, oxygen, sulfur, nitrogen and phosphorus nucleophiles. It reacts with magnesium to form the Grignard reagent, methyl-magnesium iodide used in organic synthesis. It also finds applications as an intermediate in the manufacture of pharmaceuticals and in phase-transfer catalysts. Methyl iodide can also be used as a kind of pesticide used to control insects, plant parasitic nematodes, soil borne pathogens, and weed seeds in vegetables. It can be used in the field growing strawberries, peppers, nut crops, tomatoes, grape vines, ornamentals and turf and nursery growing strawberries, stone fruits, tree nuts, and conifer trees. Its fumigant action is thought to be via the nucleophilic displacement(SN2) reaction in various amino acids and peptides within target organisms. It can also be used as a fire extinguisher.
