5,5,6,6,7,7,8,8,8-Nonafluorooctane-2,4-dione (CAS 355-84-0) is a high-purity analytical reference standard with the molecular formula C8H5F9O2 and a molecular weight of 304.11 g/mol.
5,5,6,6,7,7,8,8,8-Nonafluorooctane-2,4-dione (C8H5F9O2) contains a carboxylic acid 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.
