Chemical Structure
Description
The molecular framework of Potassium tetrakis(perfluorophenyl)borate (C24BF20K) is characterized by fluorine substitution, a polycyclic aromatic system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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.
Potassium tetrakis(perfluorophenyl)borate (CAS 89171-23-3) is a high-purity analytical reference standard with the molecular formula C24BF20K and a molecular weight of 718.13 g/mol.
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.
As a certified reference material (CRM), Potassium tetrakis(perfluorophenyl)borate 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.
