Chemical Structure
Description
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.
Potassium (z)-(2-bromo-2-phenylvinyl)trifluoroborate (CAS 219718-89-5), molecular formula C8H6BBrF3K and molecular weight 288.94 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Potassium (z)-(2-bromo-2-phenylvinyl)trifluoroborate (C8H6BBrF3K) is characterized by a salt form, fluorine/bromine substitution, an aromatic ring system. 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 (z)-(2-bromo-2-phenylvinyl)trifluoroborate 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.
