5-Hydroxy-2-isopropylbenzenesulfonamide (CAS 1243475-96-8), molecular formula C9H13NO3S and molecular weight 215.27 g/mol, is a CATO reference standard with documented purity and traceability.
5-Hydroxy-2-isopropylbenzenesulfonamide (C9H13NO3S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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.
