Sodium ((4-aminophenyl)sulfonyl)(3-methyl-1-phenyl-1H-pyrazol-5-yl)amide (CAS 18179-65-2), molecular formula C16H15N4O2SNa and molecular weight 350.37 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Sodium ((4-aminophenyl)sulfonyl)(3-methyl-1-phenyl-1H-pyrazol-5-yl)amide (C16H15N4O2SNa) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 11.5, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 350.37 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
