The occurrence of Methyl 6-amino-5-cyano-2-{[(3-cyano-6-methylpyridin-2-yl)sulfanyl]methyl}-4-(4-methoxyphenyl)-4H-pyran-3-carboxylate is closely related to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Methyl 6-amino-5-cyano-2-{[(3-cyano-6-methylpyridin-2-yl)sulfanyl]methyl}-4-(4-methoxyphenyl)-4H-pyran-3-carboxylate (CAS 489416-89-9) is a high-purity analytical reference standard with the molecular formula C23H20N4O4S and a molecular weight of 448.49 g/mol.
The molecular framework of Methyl 6-amino-5-cyano-2-{[(3-cyano-6-methylpyridin-2-yl)sulfanyl]methyl}-4-(4-methoxyphenyl)-4H-pyran-3-carboxylate (C23H20N4O4S) is characterized by a flavonoid core, an amide group, a sulfone 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
