Chemical Structure
Description
The occurrence of 5,6,7-Trihydroxy-2-(2-hydroxyphenyl)-4H-chromen-4-one is closely related to a flavonoid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 5,6,7-Trihydroxy-2-(2-hydroxyphenyl)-4H-chromen-4-one (CAS 3951-44-8), a certified reference material (molecular formula C15H10O6, MW 286.24 g/mol) for analytical method development and quality control.
The molecular framework of 5,6,7-Trihydroxy-2-(2-hydroxyphenyl)-4H-chromen-4-one (C15H10O6) 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
