7-Bromo-1H-thieno[3,2-d][1,3]oxazine-2,4-dione (CAS 2230138-52-8), molecular formula C6H2BrNO3S and molecular weight 248.05 g/mol, is a CATO reference standard with documented purity and traceability.
7-Bromo-1H-thieno[3,2-d][1,3]oxazine-2,4-dione (C6H2BrNO3S) contains an amide group, a sulfone group, 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).
CATO manufactures 7-Bromo-1H-thieno[3,2-d][1,3]oxazine-2,4-dione 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.
