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.
4-(3-(3-((3,5-Dimethyl-1H-pyrazol-1-yl)methyl)phenyl)-1,2,4-oxadiazol-5-yl)-2,6-difluorophenol (CAS 1798004-94-0) is a high-purity analytical reference standard with the molecular formula C20H16F2N4O2 and a molecular weight of 382.36 g/mol.
4-(3-(3-((3,5-Dimethyl-1H-pyrazol-1-yl)methyl)phenyl)-1,2,4-oxadiazol-5-yl)-2,6-difluorophenol (C20H16F2N4O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
