Chemical Structure
Description
1-{[1,1'-biphenyl]-4-yl}-2-(4-{[3-chloro-5-(trifluoromethyl)pyridin-2-yl]methyl}phenoxy)ethan-1-one (CAS 339106-60-4), molecular formula C27H19ClF3NO2 and molecular weight 481.89 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C27H19ClF3NO2, 1-{[1,1'-biphenyl]-4-yl}-2-(4-{[3-chloro-5-(trifluoromethyl)pyridin-2-yl]methyl}phenoxy)ethan-1-one contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 481.89 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
