Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2-[Methyl-(5-nitro-pyridin-2-yl)-amino]ethanol (CAS 25948-15-6) is a high-purity analytical reference standard with the molecular formula C17H22N6O6 and a molecular weight of 406.39 g/mol.
2-[Methyl-(5-nitro-pyridin-2-yl)-amino]ethanol (C17H22N6O6) contains a flavonoid core, 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).
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.
