Description
Compared with other compounds in its class, the molecular weight of 410.58 g/mol gives (3aR,4S,5R,6aS)-5-[[(1,1-Dimethylethyl)diphenylsilyl]oxy]hexahydro-4-(hydroxymethyl)-2H-cyclopenta[b]furan-2-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
(3aR,4S,5R,6aS)-5-[[(1,1-Dimethylethyl)diphenylsilyl]oxy]hexahydro-4-(hydroxymethyl)-2H-cyclopenta[b]furan-2-one (CAS 618386-94-0), molecular formula C24H30O4Si and molecular weight 410.58 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (3aR,4S,5R,6aS)-5-[[(1,1-Dimethylethyl)diphenylsilyl]oxy]hexahydro-4-(hydroxymethyl)-2H-cyclopenta[b]furan-2-one (C24H30O4Si) is characterized by a flavonoid 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.
