Hexafluorozirconic acid solution CAS 12021-95-3

Description

The occurrence of Hexafluorozirconic acid solution is closely related to fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Hexafluorozirconic acid solution (CAS 12021-95-3) is a high-purity analytical reference standard with the molecular formula F4ZrHF and a molecular weight of 187.22 g/mol.

The molecular framework of Hexafluorozirconic acid solution (F4ZrHF) is characterized by fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
