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-(benzyloxy)-2-phenylhexahydropyrano[3,2-d][1,3]dioxine-7,8-diol.
CATO supplies (4AR,6S,7R,8R,8aR)-6-(benzyloxy)-2-phenylhexahydropyrano[3,2-d][1,3]dioxine-7,8-diol (CAS 57783-86-5), a certified reference material (molecular formula C20H22O6, MW 358.39 g/mol) for analytical method development and quality control.
The molecular framework of (4AR,6S,7R,8R,8aR)-6-(benzyloxy)-2-phenylhexahydropyrano[3,2-d][1,3]dioxine-7,8-diol (C20H22O6) 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).
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), (4AR,6S,7R,8R,8aR)-6-(benzyloxy)-2-phenylhexahydropyrano[3,2-d][1,3]dioxine-7,8-diol 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.
