Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2-Ethoxy-2-(trifluoromethyl)cyclopentan-1-one (CAS 2812356-11-7), molecular formula C8H11F3O2 and molecular weight 196.17 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C8H11F3O2, 2-Ethoxy-2-(trifluoromethyl)cyclopentan-1-one 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 196.17 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.
