The occurrence of Diethyl ((phenylthio)methyl)phosphonate is closely related to a sulfone group, a phosphonate group, a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Diethyl ((phenylthio)methyl)phosphonate (CAS 38066-16-9) is a high-purity analytical reference standard with the molecular formula C11H17O3PS and a molecular weight of 260.29 g/mol.
Based on its molecular formula C11H17O3PS, Diethyl ((phenylthio)methyl)phosphonate contains a sulfone group, a phosphonate group, a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 260.29 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures Diethyl ((phenylthio)methyl)phosphonate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
