Chemical Structure
Description
(S)-3-(Fmoc-amino)-4-(2-fluorophenyl)butanoic Acid (C25H22FNO4) contains a flavonoid core, an amide group, 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
(S)-3-(Fmoc-amino)-4-(2-fluorophenyl)butanoic Acid (CAS 270596-49-1), molecular formula C25H22FNO4 and molecular weight 419.44 g/mol, is a CATO reference standard with documented purity and traceability.
