4-Bromo-N-(4-(2,5-dimethyl-1H-pyrrol-1-yl)phenyl)benzenesulfonamide (CAS 866156-51-6) is a high-purity analytical reference standard with the molecular formula C18H17BrN2O2S and a molecular weight of 405.31 g/mol.
4-Bromo-N-(4-(2,5-dimethyl-1H-pyrrol-1-yl)phenyl)benzenesulfonamide (C18H17BrN2O2S) contains a steroid 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, 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
