Demeton-S-methyl sulfone Usage And Synthesis
DescriptionDemeton-S-methyl sulfone is an organophosphate insecticide. Very little data is available regarding its environmental fate or its ecotoxicology. Demeton-O-methyl sulfone is highly toxic if consumed, is an acetylcholinesterase inhibitor and a neurotoxin.
UsesA metabolite of Demeton-S-methyl (D231370). An organophosphorus pesticide biomarker.
Production MethodsDemeton-S-methyl sulfone is commercially produced by oxidizing demeton-S-methyl, an organophosphorothioate compound, to its sulfone derivative using strong oxidising agents such as hydrogen peroxide or peracids. The process begins with the synthesis of demeton-S-methyl via the reaction of O,O-dimethyl phosphorothioate with 2-(ethylthio)ethanol. This intermediate is then subjected to controlled oxidation, converting the sulphur atom to a sulfone group while preserving the phosphoric ester structure. The reaction is typically carried out in organic solvents under mild heating, followed by purification through crystallisation or distillation.
DefinitionChEBI: Demeton-S-methylsulphon is a sulfone.
Mechanism of actionSystemic with contact and stomach action. Acetylcholinesterase (AChE) inhibitor.
Safety ProfilePoison by ingestion, inhalation, intraperitoneal, and intravenous routes. Moderately toxic by skin contact. Mutation data reported. An insecticide. When heated to decomposition it emits very toxic fumes of POx and SOx. See also DEMETON-0 + DEMETON-S and other demeton entries.
