The molecular framework of 2-Methoxyethyl 1,4-dihydro-5-methyl-4-oxo-2-(3-pyridinyl)thieno[2,3-d]pyrimidine-6-carboxylate (C16H15N3O4S) 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).
