| Hazard Information | Back Directory | [General Description]
A colorless to light amber liquid with a disagreeable odor. Density 1.196 g/cm3. Boiling point 120°F.Flash point below 100°F. Insoluble in water but soluble in most organic solvents. May be highly toxic and irritating to the eyes and lungs. Used as an intermediate for pesticides, as an oil and gasoline additive, and as a flame retardant. | [Reactivity Profile]
DIETHYLTHIOPHOSPHORYL CHLORIDE(2524-04-1) is incompatible with bases (including amines), with strong oxidizing agents, and with alcohols. May react vigorously or explosively if mixed with diisopropyl ether or other ethers in the presence of trace amounts of metal salts [J. Haz. Mat., 1981, 4, 291]. | [Air & Water Reactions]
Highly flammable. Insoluble in water but soluble in most organic solvents. Contact with moisture in the air produces highly corrosive and toxic fumes containing hydrogen chloride. Decomposes in water producing acidic products. | [Health Hazard]
TOXIC; inhalation, ingestion or contact (skin, eyes) with vapors, dusts or substance may cause severe injury, burns or death. Bromoacetates and chloroacetates are extremely irritating/lachrymators. Reaction with water or moist air will release toxic, corrosive or flammable gases. Reaction with water may generate much heat that will increase the concentration of fumes in the air. Fire will produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution. | [Fire Hazard]
HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames. Vapors form explosive mixtures with air: indoors, outdoors and sewers explosion hazards. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapors may travel to source of ignition and flash back. Substance will react with water (some violently) releasing flammable, toxic or corrosive gases and runoff. Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated or if contaminated with water. | [Chemical Properties]
CLEAR COLORLESS TO LIGHT YELLOW LIQUID | [Uses]
Diethyl Chlorothiophosphate is used in the preparation of various organophosporus insecticide including Flupyrazofos (F598620) and Chlorpyrifos (C425300). | [Flammability and Explosibility]
Nonflammable |
