Chemical Structure

Potassium 2,2,3,4,4,4-hexafluorobutyrate CAS 1309602-83-2 chemical structure

Description

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

Potassium 2,2,3,4,4,4-hexafluorobutyrate (CAS 1309602-83-2), molecular formula C4H2F6O2K and molecular weight 235.14 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Potassium 2,2,3,4,4,4-hexafluorobutyrate (C4H2F6O2K) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, 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.

As a certified reference material (CRM), Potassium 2,2,3,4,4,4-hexafluorobutyrate 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.
