2-Amino-4-(4-chlorophenyl)-6-(hydroxymethyl)-8-oxo-4H,8H-pyrano[3,2-b]pyran-3-carbonitrile CAS 194282-57-0 chemical structure

Description

2-Amino-4-(4-chlorophenyl)-6-(hydroxymethyl)-8-oxo-4H,8H-pyrano[3,2-b]pyran-3-carbonitrile (CAS 194282-57-0) is a high-purity analytical reference standard with the molecular formula C16H11ClN2O4 and a molecular weight of 330.72 g/mol.

2-Amino-4-(4-chlorophenyl)-6-(hydroxymethyl)-8-oxo-4H,8H-pyrano[3,2-b]pyran-3-carbonitrile (C16H11ClN2O4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
