Chemical Structure
Description
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.
CATO supplies N-(2-(3,5-Dimethyl-1H-pyrazol-1-yl)ethyl)-2-methoxy-5-methylbenzenesulfonamide (CAS 1235201-88-3), a certified reference material (molecular formula C15H21N3O3S, MW 323.41 g/mol) for analytical method development and quality control.
N-(2-(3,5-Dimethyl-1H-pyrazol-1-yl)ethyl)-2-methoxy-5-methylbenzenesulfonamide (C15H21N3O3S) 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.
