3-(2-Chlorophenyl)-5-[(1Z)-1-(dimethylamino)-4,4,4-trifluoro-3-oxobut-1-en-2-yl]-1,2-oxazole-4-carbonitrile (CAS 339106-73-9) is a high-purity analytical reference standard with the molecular formula C16H11ClF3N3O2 and a molecular weight of 369.73 g/mol.
3-(2-Chlorophenyl)-5-[(1Z)-1-(dimethylamino)-4,4,4-trifluoro-3-oxobut-1-en-2-yl]-1,2-oxazole-4-carbonitrile (C16H11ClF3N3O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine 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.
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.
