The molecular framework of (4S,5R)-4,5-Dihydroxy-6-(hydroxymethyl)-4,5-dihydropyridazin-3(2H)-one (C5H8N2O4) is characterized by a carbohydrate-derived structure, an amide group. 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).
