Description

Compared with other compounds in its class, the molecular weight of 278.33 g/mol gives 5-Ethyl-6-hydroxy-3-(2-methoxyphenyl)-2-sulfanyl-3,4-dihydropyrimidin-4-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

5-Ethyl-6-hydroxy-3-(2-methoxyphenyl)-2-sulfanyl-3,4-dihydropyrimidin-4-one (CAS 1235441-75-4) is a high-purity analytical reference standard with the molecular formula C13H14N2O3S and a molecular weight of 278.33 g/mol.

The molecular framework of 5-Ethyl-6-hydroxy-3-(2-methoxyphenyl)-2-sulfanyl-3,4-dihydropyrimidin-4-one (C13H14N2O3S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
