(2R,3S,4R,5R)-5-(benzyloxymethyl)-3-fluoro-3-methyl-4-triisopropylsilyloxy-tetrahydrofuran-2-ol CAS 1583260-37-0 chemical structure

Description

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.

(2R,3S,4R,5R)-5-(benzyloxymethyl)-3-fluoro-3-methyl-4-triisopropylsilyloxy-tetrahydrofuran-2-ol (CAS 1583260-37-0) is a high-purity analytical reference standard with the molecular formula C22H43FO4Si and a molecular weight of 418.66 g/mol.

Based on its molecular formula C22H43FO4Si, (2R,3S,4R,5R)-5-(benzyloxymethyl)-3-fluoro-3-methyl-4-triisopropylsilyloxy-tetrahydrofuran-2-ol contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 418.66 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
