Chemical Structure
Description
The molecular framework of (βS,1R,3aS,4E,7aR)-4-[[(6S)-6-[[(tert-Butyldimethylsilyloxy]-1,3,4,5,6,7-hexahydro-2,2-dioxidobenzo[c]thien-1-yl]methylene]octahydro-β,7a-dimethyl-1H-Indene-1-ethanol (C28H48O4SSi) is characterized by a steroid core, a sulfone group, 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).
(βS,1R,3aS,4E,7aR)-4-[[(6S)-6-[[(tert-Butyldimethylsilyloxy]-1,3,4,5,6,7-hexahydro-2,2-dioxidobenzo[c]thien-1-yl]methylene]octahydro-β,7a-dimethyl-1H-Indene-1-ethanol (CAS 344798-31-8), molecular formula C28H48O4SSi and molecular weight 508.83 g/mol, is a CATO reference standard with documented purity and traceability.
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), (βS,1R,3aS,4E,7aR)-4-[[(6S)-6-[[(tert-Butyldimethylsilyloxy]-1,3,4,5,6,7-hexahydro-2,2-dioxidobenzo[c]thien-1-yl]methylene]octahydro-β,7a-dimethyl-1H-Indene-1-ethanol 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.
