Chemical Structure
Description
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.
893443-18-0 1-Ethyl-1-methylpyrrolidinium trifluoromethanesulfonate DTXSID9049372 (CAS 893443-18-0), molecular formula CF3O3SC7H16N and molecular weight 263.27 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula CF3O3SC7H16N, 893443-18-0 1-Ethyl-1-methylpyrrolidinium trifluoromethanesulfonate DTXSID9049372 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 263.27 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
