N-(2,3-dimethoxybenzyl)-2-((3-methyl-4-oxo-7-(p-tolyl)-3,4-dihydrothieno[3,2-d]pyrimidin-2-yl)thio)acetamide (CAS 1040675-53-3) is a high-purity analytical reference standard with the molecular formula C25H25N3O4S2 and a molecular weight of 495.61 g/mol.
The molecular framework of N-(2,3-dimethoxybenzyl)-2-((3-methyl-4-oxo-7-(p-tolyl)-3,4-dihydrothieno[3,2-d]pyrimidin-2-yl)thio)acetamide (C25H25N3O4S2) is characterized by a flavonoid core, 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.
