Compared with other compounds in its class, the molecular weight of 243.32 g/mol gives 2-Isopropyl-4-methoxy-5-methylbenzenesulfonamide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-Isopropyl-4-methoxy-5-methylbenzenesulfonamide (CAS 1504951-37-4) is a high-purity analytical reference standard with the molecular formula C11H17NO3S and a molecular weight of 243.32 g/mol.
2-Isopropyl-4-methoxy-5-methylbenzenesulfonamide (C11H17NO3S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
