2-hydroxy-4-amino-5-nitropyridine 4-Amino-5-nitro-2-pyridinol 4-amino-5-nitropyridin-2-ol 99479-77-3 (CAS 99479-77-3) is a high-purity analytical reference standard with the molecular formula C5H5N3O3 and a molecular weight of 155.11 g/mol.

The molecular framework of 2-hydroxy-4-amino-5-nitropyridine 4-Amino-5-nitro-2-pyridinol 4-amino-5-nitropyridin-2-ol 99479-77-3 (C5H5N3O3) is characterized by an amino-acid-derived structure, 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).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
