Chemical Structure
Description
[(2R,3R,5S)-2-(benzyloxymethyl)-4,4-difluoro-5-hydroxy-tetrahydrofuran-3-yl] benzoate (C19H30F2O5) contains a steroid core, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point, 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.
