Description

Compared with other compounds in its class, the molecular weight of 377.37 g/mol gives 2-({[(9h-fluoren-9-yl)methoxy]carbonyl}amino)-5-fluorobenzoic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-({[(9h-fluoren-9-yl)methoxy]carbonyl}amino)-5-fluorobenzoic acid (CAS 1185296-60-9), molecular formula C22H16FNO4 and molecular weight 377.37 g/mol, is a CATO reference standard with documented purity and traceability.

2-({[(9h-fluoren-9-yl)methoxy]carbonyl}amino)-5-fluorobenzoic acid (C22H16FNO4) 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
