377-38-8 IS19QHB8AK Perfluorosuccinic acid Succinic acid, tetrafluoro- Tetrafluorosuccinic acid Butanedioic acid, 2,2,3,3-tetrafluoro- Butanedioic acid, tetrafluoro- 4-02-00-01926 (Beilstein Handbook Reference) AI3-19370 BRN 1790197 EINECS 206-820-7 NSC 3238 Succinic acid, perfluoro- UNII-IS19QHB8AK (C4H2F4O4) contains a carbohydrate-derived structure, 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.
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.
