Phosphorothioic acid, O,O-diethyl O-[2-(ethylsulfonyl)ethyl] ester

Description:

Phosphorothioic acid, O,O-diethyl O-[2-(ethylsulfonyl)ethyl] ester, commonly known by its CAS number 4891-54-7, is an organophosphorus compound characterized by its phosphorothioate structure. This compound features a phosphorus atom bonded to sulfur and oxygen, with two ethyl groups and a sulfonyl-substituted ethyl group attached. It is typically a colorless to pale yellow liquid with a distinct odor. The presence of the phosphorothioate functional group imparts specific biological activity, often associated with insecticidal and herbicidal properties. This compound is soluble in organic solvents but has limited solubility in water. It is important to handle it with care due to its potential toxicity and environmental impact, as organophosphates can inhibit acetylcholinesterase, leading to neurotoxic effects. Safety measures should be observed when working with this substance, including the use of personal protective equipment and proper storage conditions to prevent degradation and exposure.
