(4aR,8R,8aS)-2,2-Dimethyl-4,4a,8,8a-tetrahydropyrano[3,2-d][1,3]dioxin-8-yl acetate (CAS 97747-17-6) is a high-purity analytical reference standard with the molecular formula C11H16O5 and a molecular weight of 228.24 g/mol.
The molecular framework of (4aR,8R,8aS)-2,2-Dimethyl-4,4a,8,8a-tetrahydropyrano[3,2-d][1,3]dioxin-8-yl acetate (C11H16O5) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. 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).
CATO manufactures (4aR,8R,8aS)-2,2-Dimethyl-4,4a,8,8a-tetrahydropyrano[3,2-d][1,3]dioxin-8-yl acetate 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.
