Chemical Structure
Description
CATO supplies 5,7-Dihydroxy-4-oxo-2-phenyl-4H-chromen-6-yl hydrogen sulfate (CAS 47363-07-5), a certified reference material (molecular formula C15H10O8S, MW 350.30 g/mol) for analytical method development and quality control.
The molecular framework of 5,7-Dihydroxy-4-oxo-2-phenyl-4H-chromen-6-yl hydrogen sulfate (C15H10O8S) 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
