Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 5,7-Dihydroxy-2-(4-hydroxy-3-(4-hydroxy-3-methylbutyl)phenyl)-3-methoxy-4H-chromen-4-one (CAS 1372527-40-6), a certified reference material (molecular formula C21H22O7, MW 386.40 g/mol) for analytical method development and quality control.
The molecular framework of 5,7-Dihydroxy-2-(4-hydroxy-3-(4-hydroxy-3-methylbutyl)phenyl)-3-methoxy-4H-chromen-4-one (C21H22O7) is characterized by a flavonoid core, 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).
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.
