| | Chlorthiophos Chemical Properties |
| | Chlorthiophos Usage And Synthesis |
| Chemical Properties | Chlorthiophos is a yellowish-brown liquid. boiling point = 153-158°C @ 13 mmHg, and crystallizes at less than 25°C. Hazard identification (based on NFPA-704 M Rating System): Health 3, flammability 1, reactivity 0 | | Definition | ChEBI: Chlorthiophos is an organic thiophosphate. | | General Description | Yellow-brown liquid which tends to crystallize at less than 77F. Used as an insecticide and acaricide. | | Reactivity Profile | Organophosphates, such as Chlorthiophos, 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 | Classified as extremely hazardous by the World Health Organization(Non-Specific -- Organophosphorus Pesticide) Organic phosphorus insecticides are absorbed by the skin, as well as by the respiratory and gastrointestinal tracts. They are cholinesterase inhibitors. | | Fire Hazard | (Non-Specific -- Organophosphorus Pesticide, Liquid, n.o.s.) Container may explode in heat of fire. | | Potential Exposure | A potential danger to those involved in the manufacture, formulation, and application of this insecticide and acaricide. | | Shipping | UN3018 Organophosphorus pesticides, liquid, toxic, Hazard Class: 6.1; Labels: 6.1-Poisonous materials | | Incompatibilities | Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides. Strong oxidizers may cause release of toxic phosphorus oxides. Organophosphates, in the presence of strong reducing agents such as hydrides, may form highly toxic and flammable phosphine gas. Keep away from alkaline materials. | | Waste Disposal | In accordance with 40CFR165 recommendations for the disposal of pesticides and pesticide containers. Must be disposed properly by following package label directions or by contacting your local or federal environmental control agency, or by contacting your regional EPA office. |
