Dimethyl chlorothiophosphate Usage And Synthesis
- Chemical Propertiesclear colorless to light yellow liquid
- General DescriptionColorless 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 ProfileOrganothiophosphates, 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 HazardDimethyl chlorothiophosphate is a strong irritant to the eyes, skin, and mucous membranes.
- Fire HazardDimethyl 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 ProfilePoison by inhalation. Moderately toxic by ingestion and skin contact. Corrosive. When heated to decomposition it emits very toxic fumes of Cl-, POx, and SOx
