Chemical Structure
Description
2-Ethyl-5-methyl-1h-imidazol-3-ium tetraphenylborate (C24H20BC6H11N2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. 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.
2-Ethyl-5-methyl-1h-imidazol-3-ium tetraphenylborate (CAS 53831-70-2), molecular formula C24H20BC6H11N2 and molecular weight 430.40 g/mol, is a CATO reference standard with documented purity and traceability.
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), 2-Ethyl-5-methyl-1h-imidazol-3-ium tetraphenylborate 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.
