Chemical Structure

(3R,5R,8S,10S,13S,14S)-10,13-Dimethyl-17-oxo-2,3,4,5,6,7,8,10,12,13,14,15,16,17-tetradecahydro-1H-cyclopenta[a]phenanthren-3-yl acetate CAS 104534-37-4 chemical structure

Description

Owing to a steroid core, a hydroxyl group, an ether linkage, (3R,5R,8S,10S,13S,14S)-10,13-Dimethyl-17-oxo-2,3,4,5,6,7,8,10,12,13,14,15,16,17-tetradecahydro-1H-cyclopenta[a]phenanthren-3-yl acetate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 330.46 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

CATO supplies (3R,5R,8S,10S,13S,14S)-10,13-Dimethyl-17-oxo-2,3,4,5,6,7,8,10,12,13,14,15,16,17-tetradecahydro-1H-cyclopenta[a]phenanthren-3-yl acetate (CAS 104534-37-4), a certified reference material (molecular formula C21H30O3, MW 330.46 g/mol) for analytical method development and quality control.

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.
