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

Hazard Class: 6.1; Labels: 6.1-Poisonous materials
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.
Production Methods
Endothion is commercially produced through a synthesis involving organophosphorus chemistry. The process typically starts with the formation of O,O-dimethyl phosphorothioate, which is then reacted with a pyrone derivative, specifically, 2-(mercaptomethyl)-5-methoxy-4H-pyran-4-one. This reaction yields the final compound.
Mechanism of action
Systemic. Acetylcholinesterase (AchE) inhibitor.
