Hazard InformationBack Directory
【General Description】

Slightly brownish crystals with a slight sulfurous odor. Used for the control of a wide variety of livestock insects including cattle grubs, lice, scabies, flies, and ticks; the common ectoparasites of sheep, goats, horse, swine, and poultry as well as for screwworms in all these animals.
【Reactivity Profile】

Organothiophosphates, such as COUMAPHOS(56-72-4), 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. COUMAPHOS(56-72-4) reacts with strong oxidizing agents and alkaline materials.
【Air & Water Reactions】

Insoluble in water. This compound hydrolyzes slowly under alkaline conditions.
【Health Hazard】

Very toxic, probable oral lethal dose is 50-500 mg/kg, or between 1 teaspoonful and 1 oz. for a 70 kg (150 lb.) person. May be fatal if inhaled, swallowed, or absorbed through skin. Contact may cause burns to skin and eyes.
【Fire Hazard】

When heated to decomposition, COUMAPHOS emits very toxic fumes of sulfur oxides, phosphorus oxides, and chlorides. Incompatible with piperonyl butoxide. Stable in water.
