Description
CATO supplies 1-(2,4-Difluorophenyl)-6-oxo-4-(trifluoromethyl)-N-(4-(trifluoromethyl)phenyl)-1,6-dihydropyridazine-3-carboxamide (CAS 477859-68-0), a certified reference material (molecular formula C19H9F8N3O2, MW 463.28 g/mol) for analytical method development and quality control.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution, 1-(2,4-Difluorophenyl)-6-oxo-4-(trifluoromethyl)-N-(4-(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 463.28 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
