(10R,13R,14R,17R)-17-((2R,5R,E)-5,6-dimethylhept-3-en-2-yl)-3,5,9-trihydroxy-10,13-dimethyl-2,3,4,5,9,11,12,13,14,15,16,17-dodecahydro-1H-cyclopenta[a]phenanthren-6(10H)-one 88191-14-4 (CAS 88191-14-4), molecular formula C28H44O4 and molecular weight 444.65 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C28H44O4, (10R,13R,14R,17R)-17-((2R,5R,E)-5,6-dimethylhept-3-en-2-yl)-3,5,9-trihydroxy-10,13-dimethyl-2,3,4,5,9,11,12,13,14,15,16,17-dodecahydro-1H-cyclopenta[a]phenanthren-6(10H)-one 88191-14-4 contains a steroid core, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 444.65 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
