Description

The molecular framework of Ethyl 2-(2-((3-methyl-4-oxo-7-phenyl-3,4-dihydrothieno[3,2-d]pyrimidin-2-yl)thio)acetamido)benzoate (C24H21N3O4S2) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
