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 4-Bromo-N-((4-ethyl-5-thioxo-4,5-dihydro-1H-1,2,4-triazol-3-yl)methyl)benzenesulfonamide.
4-Bromo-N-((4-ethyl-5-thioxo-4,5-dihydro-1H-1,2,4-triazol-3-yl)methyl)benzenesulfonamide (CAS 338954-10-2), molecular formula C11H13BrN4O2S2 and molecular weight 377.28 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 4-Bromo-N-((4-ethyl-5-thioxo-4,5-dihydro-1H-1,2,4-triazol-3-yl)methyl)benzenesulfonamide (C11H13BrN4O2S2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 377.28 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.
