Description
CATO manufactures 5,7-Dibromo-2,3-diphenylquinoxaline 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.
CATO supplies 5,7-Dibromo-2,3-diphenylquinoxaline (CAS 313067-47-9), a certified reference material (molecular formula C20H12Br2N2, MW 440.13 g/mol) for analytical method development and quality control.
5,7-Dibromo-2,3-diphenylquinoxaline (C20H12Br2N2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; 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.
