N-(5-Bromo-3-pyridyl)benzenesulfonamide, 97% (CAS 1084-12-4) is a high-purity analytical reference standard with the molecular formula C11H9BrN2O2S and a molecular weight of 313.17 g/mol.
N-(5-Bromo-3-pyridyl)benzenesulfonamide, 97% (C11H9BrN2O2S) contains a nitrogen-containing heterocyclic scaffold, 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, its high carbon-to-hydrogen ratio confers good lipid solubility, 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 N-(5-Bromo-3-pyridyl)benzenesulfonamide, 97% 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.
