The occurrence of [(2R,3R,4S,5R,6S)-6-[4-(3,4-dihydroxyphenyl)-7-hydroxy-2-oxochromen-5-yl]oxy-3,4,5-trihydroxyoxan-2-yl]methyl acetate 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.
[(2R,3R,4S,5R,6S)-6-[4-(3,4-dihydroxyphenyl)-7-hydroxy-2-oxochromen-5-yl]oxy-3,4,5-trihydroxyoxan-2-yl]methyl acetate (CAS 1112383-48-8), molecular formula C23H22O12 and molecular weight 490.41 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of [(2R,3R,4S,5R,6S)-6-[4-(3,4-dihydroxyphenyl)-7-hydroxy-2-oxochromen-5-yl]oxy-3,4,5-trihydroxyoxan-2-yl]methyl acetate (C23H22O12) 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.
As a certified reference material (CRM), [(2R,3R,4S,5R,6S)-6-[4-(3,4-dihydroxyphenyl)-7-hydroxy-2-oxochromen-5-yl]oxy-3,4,5-trihydroxyoxan-2-yl]methyl acetate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
