Chemical Structure
Description
The molecular framework of 1-(1-{[(9H-fluoren-9-yl)methoxy]carbonyl}piperidin-4-yl)-1H-pyrazole-3-carboxylic acid (C24H23N3O4) is characterized by a flavonoid core, an amide 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).
