CATO supplies 3-(3-(4-(Difluoromethoxy)phenyl)-1,2,4-oxadiazol-5-yl)aniline (CAS 1708250-78-5), a certified reference material (molecular formula C15H11F2N3O2, MW 303.26 g/mol) for analytical method development and quality control.
3-(3-(4-(Difluoromethoxy)phenyl)-1,2,4-oxadiazol-5-yl)aniline (C15H11F2N3O2) contains a nitrogen-containing heterocyclic scaffold, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
