Description
As a certified reference material (CRM), Potassium trifluoro(p-tolylethynyl)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.
CATO supplies Potassium trifluoro(p-tolylethynyl)borate (CAS 664374-21-4), a certified reference material (molecular formula C9H7BF3K, MW 222.06 g/mol) for analytical method development and quality control.
Potassium trifluoro(p-tolylethynyl)borate (C9H7BF3K) contains fluorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
