Chemical Structure
Description
As a certified reference material (CRM), 52193-54-1 Pyridinium trifluoromethanesulfonate pyridine 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.
CATO supplies 52193-54-1 Pyridinium trifluoromethanesulfonate pyridine trifluoromethanesulfonate (CAS 52193-54-1), a certified reference material (molecular formula CHF3O3SC5H11N, MW 235.22 g/mol) for analytical method development and quality control.
52193-54-1 Pyridinium trifluoromethanesulfonate pyridine trifluoromethanesulfonate (CHF3O3SC5H11N) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; 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.
