Chemical Structure
Description
The molecular framework of 4-Nitrophenyl 2-acetamido-2-deoxy-3-O-(b-D-galactopyranosyl)-β-D-glucopyranoside (C20H28N2O13) 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).
