Chemical Structure
Description
The molecular framework of Potassium trifluoro(4-(methylsulfonyl)phenyl)borate (C7H7BF3O2SK) is characterized by a sulfone group, 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Potassium trifluoro(4-(methylsulfonyl)phenyl)borate (CAS 850623-40-4) is a high-purity analytical reference standard with the molecular formula C7H7BF3O2SK and a molecular weight of 262.09 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 trifluoro(4-(methylsulfonyl)phenyl)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.
