Description

Compared with other compounds in its class, the molecular weight of 294.26 g/mol gives Dimethoxyphosphorylmethyl 4-Methylbenzenesulfonate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Dimethoxyphosphorylmethyl 4-Methylbenzenesulfonate (CAS 80792-13-8) is a high-purity analytical reference standard with the molecular formula C10H15O6PS and a molecular weight of 294.26 g/mol.

Structurally, Dimethoxyphosphorylmethyl 4-Methylbenzenesulfonate (C10H15O6PS) contains a sulfone group, a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 3.5, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 294.26 g/mol, it falls into the medium-molecular-weight range. 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
