Compared with other compounds in its class, the molecular weight of 447.40 g/mol gives Ammonium (2S,4S,5R,6R)-5-acetamido-4-hydroxy-2-(4-nitrophenoxy)-6-((1R,2R)-1,2,3-trihydroxypropyl)tetrahydro-2H-pyran-2-carboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Ammonium (2S,4S,5R,6R)-5-acetamido-4-hydroxy-2-(4-nitrophenoxy)-6-((1R,2R)-1,2,3-trihydroxypropyl)tetrahydro-2H-pyran-2-carboxylate (CAS 210418-02-3), molecular formula C17H21N2O11H4N and molecular weight 447.40 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C17H21N2O11H4N, Ammonium (2S,4S,5R,6R)-5-acetamido-4-hydroxy-2-(4-nitrophenoxy)-6-((1R,2R)-1,2,3-trihydroxypropyl)tetrahydro-2H-pyran-2-carboxylate contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 447.40 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
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.
