(4AR,6S,7R,8R,8aS)-7-azido-2-phenyl-6-(phenylthio)hexahydropyrano[3,2-d][1,3]dioxin-8-yl benzoate (CAS 1301693-32-2), molecular formula C26H23N3O5S and molecular weight 489.54 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (4AR,6S,7R,8R,8aS)-7-azido-2-phenyl-6-(phenylthio)hexahydropyrano[3,2-d][1,3]dioxin-8-yl benzoate (C26H23N3O5S) is characterized by a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing 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), (4AR,6S,7R,8R,8aS)-7-azido-2-phenyl-6-(phenylthio)hexahydropyrano[3,2-d][1,3]dioxin-8-yl benzoate 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.
