Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
6-Oxo-N-phenyl-4-(trifluoromethyl)-1-(3-(trifluoromethyl)phenyl)-1,6-dihydropyridazine-3-carboxamide (CAS 477854-75-4), molecular formula C19H11F6N3O2 and molecular weight 427.30 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution, 6-Oxo-N-phenyl-4-(trifluoromethyl)-1-(3-(trifluoromethyl)phenyl)-1,6-dihydropyridazine-3-carboxamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 427.30 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
