Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including N,4-Dimethyl-N-(1-phenyl-1H-pyrazol-5-yl)benzenesulfonamide.
N,4-Dimethyl-N-(1-phenyl-1H-pyrazol-5-yl)benzenesulfonamide (CAS 374632-71-0), molecular formula C17H17N3O2S and molecular weight 327.40 g/mol, is a CATO reference standard with documented purity and traceability.
N,4-Dimethyl-N-(1-phenyl-1H-pyrazol-5-yl)benzenesulfonamide (C17H17N3O2S) contains a steroid core, 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. 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.
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.
