Chemical Structure
Description
The molecular framework of 6-Hydroxy-5-nitropyridin-2(1H)-one (C5H4N2O4) 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).
6-Hydroxy-5-nitropyridin-2(1H)-one (CAS 16013-84-6) is a high-purity analytical reference standard with the molecular formula C5H4N2O4 and a molecular weight of 156.10 g/mol.
