Chemical Structure
Description
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.
2,2,2-Trifluoro-N-(2,2,2-trifluoro-1-trifluoromethylethylidene)acetamide (CAS 52225-57-7), molecular formula C5F9NO and molecular weight 261.05 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C5F9NO, 2,2,2-Trifluoro-N-(2,2,2-trifluoro-1-trifluoromethylethylidene)acetamide contains an amide 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 261.05 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.
