Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 242.09 g/mol gives Ethyl 2,2,3,3-tetrafluoro-2-(trifluoromethoxy)propionate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Ethyl 2,2,3,3-tetrafluoro-2-(trifluoromethoxy)propionate (CAS 1526-49-4), molecular formula C6H5F7O2 and molecular weight 242.09 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C6H5F7O2, Ethyl 2,2,3,3-tetrafluoro-2-(trifluoromethoxy)propionate contains 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 242.09 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.
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.
