1-Naphthalenesulfonamide, n-methyl- (CAS 71862-34-5), molecular formula C11H11NO2S and molecular weight 221.28 g/mol, is a CATO reference standard with documented purity and traceability.
1-Naphthalenesulfonamide, n-methyl- (C11H11NO2S) contains a nitrogen-containing heterocyclic scaffold, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
