(6S,8R,9S,13S,14S,17S)-13-methyl-7,8,9,11,12,13,14,15,16,17-decahydro-6H-cyclopenta[a]phenanthrene-3,6,17-triyl triacetate (1,3,5(10)-Estratriene-3,6α,17β-Triol Triacetate) (CAS 6626-42-2), molecular formula C25H32O6 and molecular weight 428.52 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (6S,8R,9S,13S,14S,17S)-13-methyl-7,8,9,11,12,13,14,15,16,17-decahydro-6H-cyclopenta[a]phenanthrene-3,6,17-triyl triacetate (1,3,5(10)-Estratriene-3,6α,17β-Triol Triacetate) (C25H32O6) 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 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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
