CATO supplies 4-Bromo-1-methyl-5-((4-nitrophenoxy)methyl)-2-phenyl-1,2-dihydro-3H-pyrazol-3-one (CAS 946386-49-8), a certified reference material (molecular formula C17H14BrN3O4, MW 404.21 g/mol) for analytical method development and quality control.
4-Bromo-1-methyl-5-((4-nitrophenoxy)methyl)-2-phenyl-1,2-dihydro-3H-pyrazol-3-one (C17H14BrN3O4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, bromine 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.
