Chemical Structure
Description
The occurrence of Potassium (4-bromophenyl)trifluoroborate is closely related to a salt form, fluorine/bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Potassium (4-bromophenyl)trifluoroborate (CAS 374564-35-9), a certified reference material (molecular formula C6H4BBrF3K, MW 262.90 g/mol) for analytical method development and quality control.
Potassium (4-bromophenyl)trifluoroborate (C6H4BBrF3K) contains a salt form, fluorine/bromine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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 (4-bromophenyl)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.
