Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 2'-(Difluoromethoxy)-3'-(trifluoromethoxy)propiophenone (CAS 1261568-25-5), a certified reference material (molecular formula C11H9F5O3, MW 284.18 g/mol) for analytical method development and quality control.
Based on its molecular formula C11H9F5O3, 2'-(Difluoromethoxy)-3'-(trifluoromethoxy)propiophenone contains a carboxylic acid group, 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 284.18 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
