DEMETON S Usage And Synthesis
Chemical PropertiesOily Liquid
Chemical PropertiesDemeton is a light brown liquid with an odor of sulfur compounds; freezing/melting point ≤‐13 C
UsesColinesterase inhibitor. Insecticide
DefinitionChEBI: Demeton-S is an organothiophosphorus compound.
Safety ProfilePoison by ingestion, intraperitoneal, and subcutaneous routes. When heated to decomposition it emits very toxic fumes of POx and SOx. See also DEMETON-0 + DEMETON-S and other demeton entries.
Potential ExposureA potential danger to those involved in the manufacture, formulation, and application of this systemic insecticide and acaricide.

IncompatibilitiesMay form explosive mixture with air. Strong oxidizers, strong bases, soluble mercury, other pesticides, and water.
Waste DisposalThe thiono-and thiolo-isomers of this mixture are 50% hydrolyzed in 75 minutes and 0.85 min- ute, respectively @ 20℃ and pH 13. At pH 9 and 70 ℃ , the half-life of Demeton is 1.25 hour, but an pH 1-5 it is over 11 hours. Sand and rushed limestone may be added together with a flammable solvent; the resultant mixture may be burned in a furnace with afterburner and alkaline scrubber .In accordance with 40CFR165, follow recommendations for the disposal of pesticides and pesticide containers. Must be dis- posed properly by following package label directions or by contacting your local or federal environmental control agency, or by contacting your regional EPA office.
