Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
N-(tert-butyl)-2-methyl-5-oxo-5H-chromeno[2,3-b]pyridine-3-carboxamide (CAS 338417-62-2), molecular formula C18H18N2O3 and molecular weight 310.35 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of N-(tert-butyl)-2-methyl-5-oxo-5H-chromeno[2,3-b]pyridine-3-carboxamide (C18H18N2O3) is characterized by a steroid core, 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 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.
