Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 214.04 g/mol gives Heptafluorobutyric Acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Heptafluorobutyric Acid (CAS 375-22-4), molecular formula C4HF7O2 and molecular weight 214.04 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C4HF7O2, Heptafluorobutyric Acid contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 214.04 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
