Chemical Structure
Description
The molecular framework of 4-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-2-fluoro-5-methoxybenzoic acid (C23H18FNO5) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).
4-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-2-fluoro-5-methoxybenzoic acid (CAS 2243516-10-9), molecular formula C23H18FNO5 and molecular weight 407.39 g/mol, is a CATO reference standard with documented purity and traceability.
