Chemical Structure

Hexafluorophosphoric acid solution CAS 16940-81-1 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 145.97 g/mol gives Hexafluorophosphoric acid solution distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Hexafluorophosphoric acid solution (CAS 16940-81-1), molecular formula F5PHF and molecular weight 145.97 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, Hexafluorophosphoric acid solution (F5PHF) contains organophosphorus functionality, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 0, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 145.97 g/mol, it falls into the low-molecular-weight range. 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.
