cm-s2957 Chemical Properties,Uses,Production

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

Uses

Chlorthiophos is an organophosphorus pesticide.

Definition

ChEBI: Chlorthiophos is an organic thiophosphate.

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.
