CATO supplies 2-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-5-fluoro-3-methylbenzoic acid (CAS 2243516-47-2), a certified reference material (molecular formula C23H18FNO4, MW 391.39 g/mol) for analytical method development and quality control.
2-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-5-fluoro-3-methylbenzoic acid (C23H18FNO4) 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.
