Description
CATO supplies Sodium 5,5',7,7'-tetrabromo-1H,1'H-[2,2'-biindole]-3,3'-diyl bis(sulfate) (CAS 2702-33-2), a certified reference material (molecular formula C16H6Br4N2O8S2Na, MW 760.96 g/mol) for analytical method development and quality control.
Sodium 5,5',7,7'-tetrabromo-1H,1'H-[2,2'-biindole]-3,3'-diyl bis(sulfate) (C16H6Br4N2O8S2Na) contains a salt form, a flavonoid core, an amide group, a sulfone 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. 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 Sodium 5,5',7,7'-tetrabromo-1H,1'H-[2,2'-biindole]-3,3'-diyl bis(sulfate) 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.
