Chemical Structure
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.
(1S,2R,8R,10R,11S,15S)-8-methoxy-2,15-dimethylpentacyclo[8.7.0.02,7.05,7.011,15]heptadec-12-en-14-one (CAS 1309594-70-4) is a high-purity analytical reference standard with the molecular formula C20H28O2 and a molecular weight of 300.44 g/mol.
The molecular framework of (1S,2R,8R,10R,11S,15S)-8-methoxy-2,15-dimethylpentacyclo[8.7.0.02,7.05,7.011,15]heptadec-12-en-14-one (C20H28O2) is characterized by a steroid core, a hydroxyl group, an ether linkage. 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO manufactures (1S,2R,8R,10R,11S,15S)-8-methoxy-2,15-dimethylpentacyclo[8.7.0.02,7.05,7.011,15]heptadec-12-en-14-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.
