The molecular framework of 5-[4-[2-[5-(2-Methyl-1,3-dioxolan-2-yl)-2-pyridinyl]ethoxy-d4]benzyl]-2,4-thiazolidinedione (C21H18D4N2O5S) is characterized by deuterium isotope labeling, 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).
