Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
1-(2-Fluoro-4-(trifluoromethyl)phenyl)propan-1-one (CAS 208173-16-4), molecular formula C10H8F4O and molecular weight 220.16 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C10H8F4O, 1-(2-Fluoro-4-(trifluoromethyl)phenyl)propan-1-one contains a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 220.16 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.
