CATO supplies Methyl 6-amino-4-(3-(2-amino-2-oxoethoxy)phenyl)-5-cyano-2-(2-methoxy-2-oxoethyl)-4H-pyran-3-carboxylate (CAS 498536-39-3), a certified reference material (molecular formula C19H19N3O7, MW 401.37 g/mol) for analytical method development and quality control.
The molecular framework of Methyl 6-amino-4-(3-(2-amino-2-oxoethoxy)phenyl)-5-cyano-2-(2-methoxy-2-oxoethyl)-4H-pyran-3-carboxylate (C19H19N3O7) is characterized by a flavonoid 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.
