Description

CATO manufactures (4R)-Methyl 4-((3R,5R,8S,10S,13R,14S,17R)-3-acetoxy-12-hydroxy-10,13-dimethyl-2,3,4,5,6,7,8,10,12,13,14,15,16,17-tetradecahydro-1H-cyclopenta[a]phenanthren-17-yl)pentanoate 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.

(4R)-Methyl 4-((3R,5R,8S,10S,13R,14S,17R)-3-acetoxy-12-hydroxy-10,13-dimethyl-2,3,4,5,6,7,8,10,12,13,14,15,16,17-tetradecahydro-1H-cyclopenta[a]phenanthren-17-yl)pentanoate (CAS 1427582-36-2) is a high-purity analytical reference standard with the molecular formula C27H42O5 and a molecular weight of 446.62 g/mol.

Based on its molecular formula C27H42O5, (4R)-Methyl 4-((3R,5R,8S,10S,13R,14S,17R)-3-acetoxy-12-hydroxy-10,13-dimethyl-2,3,4,5,6,7,8,10,12,13,14,15,16,17-tetradecahydro-1H-cyclopenta[a]phenanthren-17-yl)pentanoate contains a steroid core, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 446.62 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
