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.
CATO supplies 1,2,3-Trimethyl-1H-imidazol-3-ium trifluoromethanesulfonate (CAS 439286-64-3), a certified reference material (molecular formula CF3O3SC6H11N2, MW 260.23 g/mol) for analytical method development and quality control.
Based on its molecular formula CF3O3SC6H11N2, 1,2,3-Trimethyl-1H-imidazol-3-ium trifluoromethanesulfonate contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 260.23 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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), 1,2,3-Trimethyl-1H-imidazol-3-ium trifluoromethanesulfonate 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.
