Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 296.04 g/mol gives Perfluoro-3,6-dioxaheptanoic Acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Perfluoro-3,6-dioxaheptanoic Acid (CAS 151772-58-6), molecular formula C5HF9O4 and molecular weight 296.04 g/mol, is a CATO reference standard with documented purity and traceability.
Perfluoro-3,6-dioxaheptanoic Acid (C5HF9O4) 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.
