2-Hydroxy-4-nitropyridine 4-Nitro-2-pyridinol 4-Nitropyrid-2-one 4487-51-8 CAS 4487-51-8

Description

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.

2-Hydroxy-4-nitropyridine 4-Nitro-2-pyridinol 4-Nitropyrid-2-one 4487-51-8 (CAS 4487-51-8) is a high-purity analytical reference standard with the molecular formula C5H4N2O3 and a molecular weight of 140.10 g/mol.

Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, 2-Hydroxy-4-nitropyridine 4-Nitro-2-pyridinol 4-Nitropyrid-2-one 4487-51-8 is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 140.10 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
