Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1,3-Dimesityl-4,5-dihydro-1H-imidazol-3-ium tetrafluoroborate.
CATO supplies 1,3-Dimesityl-4,5-dihydro-1H-imidazol-3-ium tetrafluoroborate (CAS 245679-18-9), a certified reference material (molecular formula C21H27N2BF3F, MW 394.26 g/mol) for analytical method development and quality control.
1,3-Dimesityl-4,5-dihydro-1H-imidazol-3-ium tetrafluoroborate (C21H27N2BF3F) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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), 1,3-Dimesityl-4,5-dihydro-1H-imidazol-3-ium tetrafluoroborate 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.
