The molecular framework of Methyl 3-(2-((5-(3,5-dimethoxyphenyl)-1,3,4-oxadiazol-2-yl)thio)acetamido)benzoate (C20H19N3O6S) 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
