Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (4AR,6S,7R,8R,8aR)-6-(4-methoxyphenoxy)-2-phenylhexahydropyrano[3,2-d][1,3]dioxine-7,8-diol.
(4AR,6S,7R,8R,8aR)-6-(4-methoxyphenoxy)-2-phenylhexahydropyrano[3,2-d][1,3]dioxine-7,8-diol (CAS 176299-96-0), molecular formula C20H22O7 and molecular weight 374.38 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (4AR,6S,7R,8R,8aR)-6-(4-methoxyphenoxy)-2-phenylhexahydropyrano[3,2-d][1,3]dioxine-7,8-diol (C20H22O7) 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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures (4AR,6S,7R,8R,8aR)-6-(4-methoxyphenoxy)-2-phenylhexahydropyrano[3,2-d][1,3]dioxine-7,8-diol under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
