Chemical Structure
Description
As a certified reference material (CRM), 4-Cyano-1-(difluoromethoxy)pyridin-1-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.
4-Cyano-1-(difluoromethoxy)pyridin-1-ium trifluoromethanesulfonate (CAS 2822620-31-3) is a high-purity analytical reference standard with the molecular formula C7H5F2N2OCF3O3S and a molecular weight of 320.19 g/mol.
Based on its molecular formula C7H5F2N2OCF3O3S, 4-Cyano-1-(difluoromethoxy)pyridin-1-ium trifluoromethanesulfonate contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 320.19 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.
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.
