Chemical Structure
Description
2-{[5-chloro-1-(4-methoxyphenyl)-6-oxo-1,6-dihydropyridazin-4-yl](methyl)amino}ethyl N-[3-(trifluoromethyl)phenyl]carbamate (C22H20ClF3N4O4) contains a flavonoid core, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
2-{[5-chloro-1-(4-methoxyphenyl)-6-oxo-1,6-dihydropyridazin-4-yl](methyl)amino}ethyl N-[3-(trifluoromethyl)phenyl]carbamate (CAS 477867-36-0), molecular formula C22H20ClF3N4O4 and molecular weight 496.87 g/mol, is a CATO reference standard with documented purity and traceability.
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.
