CATO supplies 3,4-Difluoro-3-(2,4-dimethylphenyl)propiophenone (CAS 898794-56-4), a certified reference material (molecular formula C17H16F2O, MW 274.31 g/mol) for analytical method development and quality control.
Based on its molecular formula C17H16F2O, 3,4-Difluoro-3-(2,4-dimethylphenyl)propiophenone contains a steroid core, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 274.31 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.
