Phosphorothioic acid, O,O-diethyl O-[4-(methylthio)phenyl] ester

Description:

Phosphorothioic acid, O,O-diethyl O-[4-(methylthio)phenyl] ester, commonly known by its CAS number 3070-15-3, is an organophosphorus compound characterized by its ester functional groups and a phosphorothioate structure. This compound typically appears as a colorless to pale yellow liquid and is known for its use as an insecticide and acaricide in agricultural applications. Its molecular structure features a phosphorus atom bonded to sulfur and oxygen, with ethyl groups and a para-substituted methylthio phenyl group, which contribute to its biological activity. The presence of the methylthio group enhances its lipophilicity, allowing for better penetration through biological membranes. As with many organophosphates, it acts by inhibiting acetylcholinesterase, leading to the accumulation of acetylcholine in synapses, which can result in neurotoxic effects. Due to its potential toxicity, appropriate safety measures should be taken when handling this compound, and it is subject to regulatory controls in many regions.
