Chemical Structure
Description
rel-(1R,4aS,9aS)-8-Hydroxy-9,10-dioxo-1,4,4a,9,9a,10-hexahydroanthracen-1-yl acetate (CAS 73794-49-7), molecular formula C16H14O5 and molecular weight 286.28 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of rel-(1R,4aS,9aS)-8-Hydroxy-9,10-dioxo-1,4,4a,9,9a,10-hexahydroanthracen-1-yl acetate (C16H14O5) 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.
