Usage

Uses

Insecticide.

General Description

Oily liquid with an amber color and an odor of sulfur. Used as an agricultural insecticide.

Reactivity Profile

DEMETON may release sulfur oxides and phosphoric acid. Solvent carrier vapors may travel on ground to ignition source. Avoid strong oxidizers. Avoid mixtures with water or polar solvents, in which sulfur is lost to oxygen, air and light, which cause hydrolysis, alkaline mixtures and oxidizing agents. [EPA, 1998].

Health Hazard

Different sources of media describe the Health Hazard of 8065-48-3 differently. You can refer to the following data:
1. DEMETON is a cholinesterase inhibitor. It is readily absorbed through the skinand is extremely toxic. Probable human lethal oral dose is 5-50 mg/kg or 7 drops to 1 teaspoonful for 150 lb. person. Acute dose is believed to be 12 to 20 mg by oral route.
2. One of the extremely toxic organophosphorus pesticides; cholinesterase inhibitor;exhibits acute, delayed, and chronic effects;toxic symptoms include headache, dizziness, muscle spasms, pinpoint pupils, blurredvision, weakness, abdominal pain, vomiting,nausea, diarrhea, and seizure; high exposuremay cause coma and death; other symptomsare chest pain, low or high blood pressure,shortness of breath, psychosis, respiratorydepression, and respiratory paralysis; readily absorbed through skin; effects may bedelayed by several hours; ingestion can causeimmediate seizure or loss of consciousness;probable oral lethal dose within the range0.4–2 g for adult humans.LD50 oral (rat): 1.7 mg/kgLD50 skin (rat): 8–14 mg/kg.

Fire Hazard

May release sulfur oxides and phosphoric acid. Solvent carrier vapors may travel on ground to ignition source. Avoid strong oxidizers. Avoid mixtures with water or polar solvents, in which sulfur is lost to oxygen, air and light, which cause hydrolysis, alkaline mixtures and oxidizing agents.
