Description

Compared with other compounds in its class, the molecular weight of 365.38 g/mol gives 2-Hydroxy-5-((4-methyl-5-(4-methylbenzyl)-6-oxo-1,6-dihydropyrimidin-2-yl)amino)benzoic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-Hydroxy-5-((4-methyl-5-(4-methylbenzyl)-6-oxo-1,6-dihydropyrimidin-2-yl)amino)benzoic acid (CAS 1417636-79-3) is a high-purity analytical reference standard with the molecular formula C20H19N3O4 and a molecular weight of 365.38 g/mol.

The molecular framework of 2-Hydroxy-5-((4-methyl-5-(4-methylbenzyl)-6-oxo-1,6-dihydropyrimidin-2-yl)amino)benzoic acid (C20H19N3O4) is characterized by a flavonoid core, an amide 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.
