1-(3,4-Dihydroxyphenyl)-3-((2R,3R,4aR,6R,7S,8S,8aR)-2-(3,4-dihydroxyphenyl)-7,8-dihydroxy-6-(hydroxymethyl)hexahydro-6H-pyrano[2,3-b][1,4]dioxin-3-yl)propan-1-one (CAS 229971-57-7), molecular formula C23H26O11 and molecular weight 478.45 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1-(3,4-Dihydroxyphenyl)-3-((2R,3R,4aR,6R,7S,8S,8aR)-2-(3,4-dihydroxyphenyl)-7,8-dihydroxy-6-(hydroxymethyl)hexahydro-6H-pyrano[2,3-b][1,4]dioxin-3-yl)propan-1-one (C23H26O11) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
As a certified reference material (CRM), 1-(3,4-Dihydroxyphenyl)-3-((2R,3R,4aR,6R,7S,8S,8aR)-2-(3,4-dihydroxyphenyl)-7,8-dihydroxy-6-(hydroxymethyl)hexahydro-6H-pyrano[2,3-b][1,4]dioxin-3-yl)propan-1-one 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.
