Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
N-(1-Hydroxy-1-phenylpropan-2-yl)-N-methylthiophene-2-sulfonamide (CAS 379726-30-4) is a high-purity analytical reference standard with the molecular formula C14H17NO3S2 and a molecular weight of 311.42 g/mol.
N-(1-Hydroxy-1-phenylpropan-2-yl)-N-methylthiophene-2-sulfonamide (C14H17NO3S2) 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).
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.
