Safety Profile
Poison by ingestion and skin contact. Mutation data reported. Caution: It is a cholinesterase inhibitor. When heated to decomposition it emits very toxic fumes of POx and SOx.

Specification
Methyl demeton methyl (CAS NO.2587-90-8) is also called 2-Methylthioethyl O,O-dimethyl phosphorothioate ; 4-01-00-02460 (Beilstein Handbook Reference) ; BRN 1707090 ; Caswell No. 369A ; Cebetox ; Cymetox ; Demephion ; Demephion-S ; EPA Pesticide Chemical Code 369200 ; Ethanethiol, 2-(methylthio)-, O,O-dimethyl phosphorothioate ; Ethanethiol, 2-(methylthio)-, S-ester with O,O-dimethyl phosphorothioate ; Isotinox ; O,O-Dimethyl S-(2-(methylthio)ethyl) phosphorothioate . Methyl demeton methyl (CAS NO.2587-90-8) is a straw-colored liquid. Methyl demeton methyl , like other thiophosphate esters, may react with strong reducing agents such as hydrides to give highly toxic and flammable phosphine gas. Partial oxidation by oxidizing agents may result in the release of toxic phosphorus oxides. May be fatal if inhaled, swallowed or absorbed through the skin. Contact may cause burns to skin and eyes. May cause respiratory failure.
Methyl demeton methyl may burn but does not ignite readily. Container may explode in heat of fire. Fire may produce irritating or poisonous gases. Runoff from fire control water may give off poisonous gases.
