118392-79-3 Dodecahydro-10,13-dimethyl-2H-cyclopenta[a]phenanthren-3(4H,9H,14H)-one [1,1'-Biphenyl]-4-carboxylic acid hexahydro-2-oxo-4-[2-[2-(phenoxymethyl)-1,3-dioxolan-2-yl]ethenyl]-2H-cyclopenta[b]furan-5-yl ester (CAS 118392-79-3), molecular formula C32H30O7 and molecular weight 526.58 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 118392-79-3 Dodecahydro-10,13-dimethyl-2H-cyclopenta[a]phenanthren-3(4H,9H,14H)-one [1,1'-Biphenyl]-4-carboxylic acid hexahydro-2-oxo-4-[2-[2-(phenoxymethyl)-1,3-dioxolan-2-yl]ethenyl]-2H-cyclopenta[b]furan-5-yl ester (C32H30O7) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
