Malathion Chemical Properties,Usage,Production

Chemical Properties
Deep Brown to Yellow Liquid
Malation is a pestanal and used primarily as an insecticide.
Used as an insecticide
ChEBI: A diester that is butanedioate substituted by a (dimethoxyphosphorothioyl)sulfanediyl group at position 2.
General Description
Yellow to dark-brown liquid with a skunk-like odor. Sinks in water. Freezing point is 37°F.
Air & Water Reactions
Insoluble in water.
Reactivity Profile
Malathion is a yellow to brown liquid that solidifies at 2.9° C, moderately toxic. Organic phosphate insecticide, acts as an inhibitor of cholinesterase. When heated to decomposition Malathion emits toxic fumes of oxides of sulfur and phosphorus [Lewis, 3rd ed., 1993, p. 789].
Health Hazard
Exposure to fumes from a fire or to liquid causes headache, blurred vision, constricted pupils of the eyes, weakness, nausea, cramps, diarrhea, and tightness in the chest. Muscles twitch and convulsions may follow. The symptoms may develop over a period of 8 hours.
