2-(3-Bromo-1-(3-chloropyridin-2-yl)-1H-pyrazol-5-yl)-6-iodo-8-methyl-4H-benzo[d][1,3]oxazin-4-one (CAS 736995-63-4), molecular formula C17H9BrClIN4O2 and molecular weight 543.54 g/mol, is a CATO reference standard with documented purity and traceability.
2-(3-Bromo-1-(3-chloropyridin-2-yl)-1H-pyrazol-5-yl)-6-iodo-8-methyl-4H-benzo[d][1,3]oxazin-4-one (C17H9BrClIN4O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine/bromine/iodine 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
CATO manufactures 2-(3-Bromo-1-(3-chloropyridin-2-yl)-1H-pyrazol-5-yl)-6-iodo-8-methyl-4H-benzo[d][1,3]oxazin-4-one under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
