Dimethyl chlorothiophosphate Chemical Properties,Usage,Production
Chemical Properties
clear colorless to light yellow liquid
General Description
Colorless to light amber liquid. Used as a chemical intermediate for insecticides, pesticides, and fungicides; oil and gasoline additives; plasticizers; corrosion inhibitors; flame retardants; and flotation agents. Not registered as a pesticide in the U.S.
Reactivity Profile
Organothiophosphates, such as Dimethyl chlorothiophosphate, 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.
Health Hazard
Dimethyl chlorothiophosphate is a strong irritant to the eyes, skin, and mucous membranes.
Fire Hazard
Dimethyl chlorothiophosphate may burn but does not ignite readily. Dimethyl chlorothiophosphate may ignite combustibles (wood, paper, oil, etc.). When heated Dimethyl chlorothiophosphate emits very toxic fumes of chlorine containing compounds, phosphorus oxides, and sulfur oxides.
Safety Profile
Poison by inhalation. Moderately toxic by ingestion and skin contact. Corrosive. When heated to decomposition it emits very toxic fumes of Cl-, POx, and SOx
