Chemical Structure
Description
The occurrence of Methyl 2-oxo-3-(phenylsulfonyl)-2H-chromene-6-carboxylate is closely related to a flavonoid core, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Methyl 2-oxo-3-(phenylsulfonyl)-2H-chromene-6-carboxylate (CAS 895645-53-1), a certified reference material (molecular formula C17H12O6S, MW 344.34 g/mol) for analytical method development and quality control.
The molecular framework of Methyl 2-oxo-3-(phenylsulfonyl)-2H-chromene-6-carboxylate (C17H12O6S) is characterized by a flavonoid core, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
