[Uses]

An active metabolite of Malathion. It is a widely used anticholinesterase phosphorothioate insecticide
[Definition]

ChEBI: Diethyl 2-[(dimethoxyphosphoryl)thio]succinate is a diester that is diethyl succinate in which position 2 is substituted by a (dimethoxyphosphoryl)thio group. It is a diester, an ethyl ester and an organic thiophosphate.
[General Description]

Colorless viscous oily liquid with a weak unpleasant odor.
[Air & Water Reactions]

MALAOXON may be sensitive to prolonged exposure to air. . Slightly water soluble.
[Reactivity Profile]

A thioorganophosphate, ester. Organophosphates are susceptible to formation of highly toxic and flammable phosphine gas in the presence of strong reducing agents such as hydrides. Partial oxidation by oxidizing agents may result in the release of toxic phosphorus oxides. Esters react with acids to liberate heat along with alcohols and acids. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. Heat is also generated by the interaction of esters with caustic solutions. Flammable hydrogen is generated by mixing esters with alkali metals and hydrides.
[Fire Hazard]

MALAOXON is probably combustible.
[Safety Profile]

Poison by ingestion and intraperitoneal routes. Experimental reproductive effects. Mutation data reported. Whenheated to decomposition it emits toxic fumes of SOx and POx.
