Description

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.

CATO supplies (3R,5S,6R,7R,8S,9S,10S,13R,14S,17R)-17-((R)-5,5-Diphenylpent-4-en-2-yl)-6-ethyl-7-hydroxy-10,13-dimethylhexadecahydro-1H-cyclopenta[a]phenanthren-3-yl acetate (CAS 1605309-10-1), a certified reference material (molecular formula C40H54O3, MW 582.85 g/mol) for analytical method development and quality control.

The molecular framework of (3R,5S,6R,7R,8S,9S,10S,13R,14S,17R)-17-((R)-5,5-Diphenylpent-4-en-2-yl)-6-ethyl-7-hydroxy-10,13-dimethylhexadecahydro-1H-cyclopenta[a]phenanthren-3-yl acetate (C40H54O3) 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 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).

As a certified reference material (CRM), (3R,5S,6R,7R,8S,9S,10S,13R,14S,17R)-17-((R)-5,5-Diphenylpent-4-en-2-yl)-6-ethyl-7-hydroxy-10,13-dimethylhexadecahydro-1H-cyclopenta[a]phenanthren-3-yl acetate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
