Chemical Structure
Description
(2S,3R,4R)-3,4-bis(benzyloxy)-2-(iodomethyl)-5-methoxytetrahydrofuran (CAS 869476-25-5) is a high-purity analytical reference standard with the molecular formula C20H23IO4 and a molecular weight of 454.30 g/mol.
Based on its molecular formula C20H23IO4, (2S,3R,4R)-3,4-bis(benzyloxy)-2-(iodomethyl)-5-methoxytetrahydrofuran contains a flavonoid core, a hydroxyl group, an ether linkage, iodine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 454.30 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
