Description

Compared with other compounds in its class, the molecular weight of 460.69 g/mol gives (1R,3R)-5-((E)-2-((1R,3aS,7aR)-1-((2R,5S,E)-6-(methoxymethoxy)-5,6-dimethylhept-3-en-2-yl)-7a-methyldihydro-1H-inden-4(2H,5H,6H,7H,7aH)-ylidene)ethylidene)cyclohexane-1,3-diol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

(1R,3R)-5-((E)-2-((1R,3aS,7aR)-1-((2R,5S,E)-6-(methoxymethoxy)-5,6-dimethylhept-3-en-2-yl)-7a-methyldihydro-1H-inden-4(2H,5H,6H,7H,7aH)-ylidene)ethylidene)cyclohexane-1,3-diol (CAS 1023889-38-4) is a high-purity analytical reference standard with the molecular formula C29H48O4 and a molecular weight of 460.69 g/mol.

The molecular framework of (1R,3R)-5-((E)-2-((1R,3aS,7aR)-1-((2R,5S,E)-6-(methoxymethoxy)-5,6-dimethylhept-3-en-2-yl)-7a-methyldihydro-1H-inden-4(2H,5H,6H,7H,7aH)-ylidene)ethylidene)cyclohexane-1,3-diol (C29H48O4) 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).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
