Description

The molecular framework of (3S,8S,9S,10R,11S,13S,14S,17S)-10,13-dimethyl-2,3,4,7,8,9,10,11,12,13,14,15,16,17-tetradecahydro-1H-cyclopenta[a]phenanthrene-3,11,17-triol 3924-22-9 5-Androsten-3-beta,11-beta,17-beta-triol (C19H30O3) is characterized by a steroid core, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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).

(3S,8S,9S,10R,11S,13S,14S,17S)-10,13-dimethyl-2,3,4,7,8,9,10,11,12,13,14,15,16,17-tetradecahydro-1H-cyclopenta[a]phenanthrene-3,11,17-triol 3924-22-9 5-Androsten-3-beta,11-beta,17-beta-triol (CAS 3924-22-9) is a high-purity analytical reference standard with the molecular formula C19H30O3 and a molecular weight of 306.44 g/mol.
