Description
Compared with other compounds in its class, the molecular weight of 231.21 g/mol gives 3-((3-Nitropyridin-2-yl)oxy)aniline distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
3-((3-Nitropyridin-2-yl)oxy)aniline (CAS 901920-06-7) is a high-purity analytical reference standard with the molecular formula C11H9N3O3 and a molecular weight of 231.21 g/mol.
3-((3-Nitropyridin-2-yl)oxy)aniline (C11H9N3O3) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
