(3aR,4R,5R,6aS)-Hexahydro-2-oxo-4-[(1E)-3-oxo-1-octen-1-yl]-2H-cyclopenta[b]furan-5-yl Ester [1,1-Biphenyl]-4-carboxylic Acid (CAS 31753-00-1), molecular formula C28H30O5 and molecular weight 446.53 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (3aR,4R,5R,6aS)-Hexahydro-2-oxo-4-[(1E)-3-oxo-1-octen-1-yl]-2H-cyclopenta[b]furan-5-yl Ester [1,1-Biphenyl]-4-carboxylic Acid (C28H30O5) is characterized by a steroid 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
