Chemical Structure

Potassium hexafluoroniobate CAS 16919-14-5 chemical structure

Description

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

Potassium hexafluoroniobate (CAS 16919-14-5) is a high-purity analytical reference standard with the molecular formula F6NbK and a molecular weight of 245.99 g/mol.

The molecular framework of Potassium hexafluoroniobate (F6NbK) 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.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), Potassium hexafluoroniobate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
