Description

Compared with other compounds in its class, the molecular weight of 288.42 g/mol gives (8R,9S,10R,13S,14S)-3-hydroxy-10,13-dimethyl-3,4,5,6,7,8,9,10,11,12,13,14,15,16-tetradecahydro-17H-cyclopenta[a]phenanthren-17-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies (8R,9S,10R,13S,14S)-3-hydroxy-10,13-dimethyl-3,4,5,6,7,8,9,10,11,12,13,14,15,16-tetradecahydro-17H-cyclopenta[a]phenanthren-17-one (CAS 76822-24-7), a certified reference material (molecular formula C19H28O2, MW 288.42 g/mol) for analytical method development and quality control.

(8R,9S,10R,13S,14S)-3-hydroxy-10,13-dimethyl-3,4,5,6,7,8,9,10,11,12,13,14,15,16-tetradecahydro-17H-cyclopenta[a]phenanthren-17-one (C19H28O2) contains a steroid core, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.

As a certified reference material (CRM), (8R,9S,10R,13S,14S)-3-hydroxy-10,13-dimethyl-3,4,5,6,7,8,9,10,11,12,13,14,15,16-tetradecahydro-17H-cyclopenta[a]phenanthren-17-one 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.
