N-(3,5-Dichlorophenyl)-4-(oxazol-2-yl)benzenesulfonamide (CAS 646040-56-4) is a high-purity analytical reference standard with the molecular formula C15H10Cl2N2O3S and a molecular weight of 369.22 g/mol.
N-(3,5-Dichlorophenyl)-4-(oxazol-2-yl)benzenesulfonamide (C15H10Cl2N2O3S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
