3-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-3-(2,4-dichlorophenyl)propanoic acid (CAS 683217-93-8), molecular formula C24H19Cl2NO4 and molecular weight 456.32 g/mol, is a CATO reference standard with documented purity and traceability.
3-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-3-(2,4-dichlorophenyl)propanoic acid (C24H19Cl2NO4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine 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).
As a certified reference material (CRM), 3-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-3-(2,4-dichlorophenyl)propanoic acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
