Safety Information of Ethyl-s-dimethylaminoethyl methylphosphonothiolate (CAS NO. 50782-69-9):
RIDADR: 2810
HazardClass: 6.1(a)
PackingGroup: I
Human poison by skin contact. Experimental poison by intraperitoneal and subcutaneous routes. An experimental teratogen. Other experimental reproductive effects. Human systemic effects by ingestion and intravenous routes: hallucinations and distorted perceptions, blood pressure increase, hypermotility, diarrhea, nausea and vomiting, visual field changes, sleep disturbance. A chemical warfare agent. A combustible liquid. When heated to decomposition it emits very toxic fumes of SO_x and NO_x.

Ethyl-s-dimethylaminoethyl methylphosphonothiolate Specification

Reactivity Profile: Organophosphates 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: Cholinesterase inhibitor. Lowest toxic oral dose (TDLO) to humans is 4 mg/kg; lowest lethal skin dose to humans (LDLO) is 86 mg/kg. Death within 15 minutes after fatal dose is absorbed.
Fire Hazard: Highly toxic nitrogen oxides and sulfur oxides. Avoid extreme heat.
