Chemical Structure
Description
[(1R,2R,3S,4S)-2-[(tert-butyldimethylsilyl)oxy]-3-fluoro-4-[(4-methoxyphenyl)methoxy]cyclopentyl]methanol (C20H39FO4Si) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
[(1R,2R,3S,4S)-2-[(tert-butyldimethylsilyl)oxy]-3-fluoro-4-[(4-methoxyphenyl)methoxy]cyclopentyl]methanol (CAS 1523530-54-2) is a high-purity analytical reference standard with the molecular formula C20H39FO4Si and a molecular weight of 390.61 g/mol.
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.
