Description

The occurrence of (8R,9S,10R,13S,14S,17R)-17-Acetyl-6-chloro-17-hydroxy-10,13-dimethyl-8,9,10,11,12,13,14,15,16,17-decahydro-3H-cyclopenta[a]phenanthren-3-one is closely related to a steroid core, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies (8R,9S,10R,13S,14S,17R)-17-Acetyl-6-chloro-17-hydroxy-10,13-dimethyl-8,9,10,11,12,13,14,15,16,17-decahydro-3H-cyclopenta[a]phenanthren-3-one (CAS 15262-77-8), a certified reference material (molecular formula C21H25ClO3, MW 360.87 g/mol) for analytical method development and quality control.

Based on its molecular formula C21H25ClO3, (8R,9S,10R,13S,14S,17R)-17-Acetyl-6-chloro-17-hydroxy-10,13-dimethyl-8,9,10,11,12,13,14,15,16,17-decahydro-3H-cyclopenta[a]phenanthren-3-one contains a steroid core, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 360.87 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.

CATO manufactures (8R,9S,10R,13S,14S,17R)-17-Acetyl-6-chloro-17-hydroxy-10,13-dimethyl-8,9,10,11,12,13,14,15,16,17-decahydro-3H-cyclopenta[a]phenanthren-3-one under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
