2-Amino-4-(2,5-difluorophenyl)-6-(hydroxymethyl)-8-oxo-4H,8H-pyrano[3,2-b]pyran-3-carbonitrile (CAS 664999-56-8) is a high-purity analytical reference standard with the molecular formula C16H10F2N2O4 and a molecular weight of 332.26 g/mol.

2-Amino-4-(2,5-difluorophenyl)-6-(hydroxymethyl)-8-oxo-4H,8H-pyrano[3,2-b]pyran-3-carbonitrile (C16H10F2N2O4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
