Hazard InformationBack Directory
[Chemical Properties]

Crystals.Very soluble in water; soluble in chloroform and ethanol.
[General Description]

White crystals with a slight odor. Used as an insecticide. Not sold in the USA or Canada.
[Reactivity Profile]

Organothiophosphates, such as endothion, 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]

endothion is poisonous to humans. Its toxic effects are most likely related to action on the nervous system.
[Fire Hazard]

(Non-Specific -- Organophosphorus Pesticide, n.o.s.) Cylinder may explode in heat or fire. Fire and runoff from fire control water may produce irritating or poisonous gases. When heated to decomposition, endothion emits very toxic fumes of phosphorous oxides and sulfur oxides.
[Hazard]

Toxic by ingestion, cholinesterase inhibitor; use may be restricted.
[Potential Exposure]

This material is a systemic insecticide. It is not sold in the United States or Canada
[First aid]

If this chemical gets into the eyes, remove any contact lenses at once and irrigate immediately for at least 15 minutes, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts the skin, remove contaminated clothing and wash immediately with soap and water. Speed in removing material from skin is of extreme importance. Shampoo hair promptly if contaminated. Speed in removing material from skin is of extreme importance. Seek medical attention immediately. If this chemical has been inhaled, remove from exposure, begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR if heart action has stopped. Transfer promptly to a medical facility. When this chemical has been swallowed, get medical attention. Give large quantities of water and induce vomiting. Do not make an unconscious person vomit. Keep victim quiet and maintain normal body temperature. Effects may be delayed; keep victim under observation

[Incompatibilities]

Contact with oxidizers may cause the release of phosphorous oxides. Contact with strong reducing agents, such as hydrides; may cause the formation of flammable and toxic phosphine gas.
[Description]

Endothion is a white crystalline solid with aslight odor. Molecular weight= 280.25; Freezing/Meltingpoint = 96C. Hazard Identification (based on NFPA-704 MRating System): Health 4, Flammability 1, Reactivity 0.Soluble in water
[Waste Disposal]

In accordance with 40CFR 165 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.
[Definition]

ChEBI: Endothion is a member of 4-pyranones.
