Chemical Structure
Description
(2S,3S,4R,5R)-2,4-bis(benzyloxy)-5-[(benzyloxy)methyl]-3-fluorooxolane (C26H45FO4) contains a steroid core, 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
(2S,3S,4R,5R)-2,4-bis(benzyloxy)-5-[(benzyloxy)methyl]-3-fluorooxolane (CAS 80765-80-6), molecular formula C26H45FO4 and molecular weight 440.63 g/mol, is a CATO reference standard with documented purity and traceability.
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.
