3-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-3-(3,4-dichlorophenyl)propanoic acid (CAS 284492-13-3), 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-(3,4-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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
