N-(9-Phenyl-9H-selenoxanthen-9-yl)benzenesulfonamide (CAS 82238-30-0), molecular formula C25H19NO2SSe and molecular weight 476.45 g/mol, is a CATO reference standard with documented purity and traceability.
N-(9-Phenyl-9H-selenoxanthen-9-yl)benzenesulfonamide (C25H19NO2SSe) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
CATO manufactures N-(9-Phenyl-9H-selenoxanthen-9-yl)benzenesulfonamide 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.
