Chemical Structure
Description
The molecular framework of N-(3,5-Dimethoxyphenyl)-2-((8-oxo-7-phenyl-7,8-dihydro-[1,2,4]triazolo[4,3-a]pyrazin-3-yl)thio)acetamide (C21H19N5O4S) 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).
