N-(5-((6-Acetamidopyridin-3-yl)oxy)-2-chlorophenyl)-3-(4-fluorophenyl)-2-oxoimidazolidine-1-carboxamide (CAS 1020536-04-2), molecular formula C23H19ClFN5O4 and molecular weight 483.88 g/mol, is a CATO reference standard with documented purity and traceability.
N-(5-((6-Acetamidopyridin-3-yl)oxy)-2-chlorophenyl)-3-(4-fluorophenyl)-2-oxoimidazolidine-1-carboxamide (C23H19ClFN5O4) 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.
As a certified reference material (CRM), N-(5-((6-Acetamidopyridin-3-yl)oxy)-2-chlorophenyl)-3-(4-fluorophenyl)-2-oxoimidazolidine-1-carboxamide 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.
