Description
4-((5-Chloro-6-oxo-1-(3-(trifluoromethyl)phenyl)-1,6-dihydropyridazin-4-yl)oxy)-3-methoxybenzaldehyde (CAS 881580-69-4), molecular formula C19H12ClF3N2O4 and molecular weight 424.76 g/mol, is a CATO reference standard with documented purity and traceability.
4-((5-Chloro-6-oxo-1-(3-(trifluoromethyl)phenyl)-1,6-dihydropyridazin-4-yl)oxy)-3-methoxybenzaldehyde (C19H12ClF3N2O4) 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 4-((5-Chloro-6-oxo-1-(3-(trifluoromethyl)phenyl)-1,6-dihydropyridazin-4-yl)oxy)-3-methoxybenzaldehyde meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
