Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 8-Bromo-5-hydroxy-6,7-dimethoxy-2-methyl-4H-chromen-4-one.
CATO supplies 8-Bromo-5-hydroxy-6,7-dimethoxy-2-methyl-4H-chromen-4-one (CAS 1295300-15-0), a certified reference material (molecular formula C12H11BrO5, MW 315.12 g/mol) for analytical method development and quality control.
8-Bromo-5-hydroxy-6,7-dimethoxy-2-methyl-4H-chromen-4-one (C12H11BrO5) contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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-5-hydroxy-6,7-dimethoxy-2-methyl-4H-chromen-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.
