2-(2-Chloro-1,1,2,2-Tetrafluoroethoxy)-1,1,2,2-Tetrafluoroethanesulfonamide CAS 144951-86-0

Description

Based on its molecular formula C4ClF8N3O3S, 2-(2-Chloro-1,1,2,2-Tetrafluoroethoxy)-1,1,2,2-Tetrafluoroethanesulfonamide contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 357.57 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.

2-(2-Chloro-1,1,2,2-Tetrafluoroethoxy)-1,1,2,2-Tetrafluoroethanesulfonamide (CAS 144951-86-0), molecular formula C4ClF8N3O3S and molecular weight 357.57 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.

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.
