Diethyl (4-(methylthio)phenyl)phosphonate CAS 77918-45-7

Description

Compared with other compounds in its class, the molecular weight of 260.29 g/mol gives Diethyl (4-(methylthio)phenyl)phosphonate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Diethyl (4-(methylthio)phenyl)phosphonate (CAS 77918-45-7) 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 (4-(methylthio)phenyl)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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
