Chemical Structure

Demeton-S Sulfoxide CAS 2496-92-6 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 274.34 g/mol gives Demeton-S Sulfoxide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Demeton-S Sulfoxide (CAS 2496-92-6) is a high-purity analytical reference standard with the molecular formula C8H19O4PS2 and a molecular weight of 274.34 g/mol.

Structurally, Demeton-S Sulfoxide (C8H19O4PS2) 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 -0.5, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 274.34 g/mol, it falls into the medium-molecular-weight range.

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.
