Chemical Structure
Description
2,5-Dibromo-N-methylbenzenesulfonamide (CAS 6318-32-7), molecular formula C7H7Br2NO2S and molecular weight 329.01 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C7H7Br2NO2S, 2,5-Dibromo-N-methylbenzenesulfonamide contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 329.01 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
