Phosphonothioic acid,phenyl-, O,O-diphenyl ester (9CI)

Description:

Phosphonothioic acid, phenyl-, O,O-diphenyl ester, commonly referred to by its CAS number 88239-51-4, is an organophosphorus compound characterized by its phosphonate structure. This substance features a phosphorus atom bonded to two phenyl groups and a thiol group, which contributes to its unique chemical properties. It is typically a colorless to pale yellow liquid with a relatively low volatility. The compound exhibits moderate to high toxicity, primarily due to its potential as an inhibitor of acetylcholinesterase, an enzyme critical for nerve function. As a result, it is important to handle this substance with caution, following appropriate safety protocols. In terms of solubility, phosphonothioic acid esters are generally soluble in organic solvents but have limited solubility in water. This compound is utilized in various applications, including as a pesticide and in chemical synthesis, owing to its reactivity and ability to form stable complexes with metal ions. Proper storage and disposal methods are essential to mitigate environmental and health risks associated with its use.
