Chemical Structure
Description
The occurrence of 8-Bromo-7-chloro-4-hydroxy-6-iodo-3-nitroquinolin-2(1H)-one is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine/bromine/iodine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 8-Bromo-7-chloro-4-hydroxy-6-iodo-3-nitroquinolin-2(1H)-one (CAS 2667057-70-5), a certified reference material (molecular formula C9H3BrClIN2O4, MW 445.39 g/mol) for analytical method development and quality control.
8-Bromo-7-chloro-4-hydroxy-6-iodo-3-nitroquinolin-2(1H)-one (C9H3BrClIN2O4) contains a nitrogen-containing heterocyclic scaffold, 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 8-Bromo-7-chloro-4-hydroxy-6-iodo-3-nitroquinolin-2(1H)-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.
