Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 331.22 g/mol gives 3-Amino-4-chloro-N-(3-chloro-4-methyl-phenyl)-benzenesulfonamide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
3-Amino-4-chloro-N-(3-chloro-4-methyl-phenyl)-benzenesulfonamide (CAS 78726-73-5), molecular formula C13H12Cl2N2O2S and molecular weight 331.22 g/mol, is a CATO reference standard with documented purity and traceability.
3-Amino-4-chloro-N-(3-chloro-4-methyl-phenyl)-benzenesulfonamide (C13H12Cl2N2O2S) 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, 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 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.
