2,2,3,3,4,4,5,5,5-nonafluoropentyl 9-(dicyanomethylidene)-2,7-dinitro-9H-fluorene-4-carboxylate (CAS 254973-33-6) is a high-purity analytical reference standard with the molecular formula C22H7F9N4O6 and a molecular weight of 594.30 g/mol.
2,2,3,3,4,4,5,5,5-nonafluoropentyl 9-(dicyanomethylidene)-2,7-dinitro-9H-fluorene-4-carboxylate (C22H7F9N4O6) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, 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.
