Chemical Structure
Description
4-Bromo-N-tert-butyl-3-methylbenzenesulfonamide (CAS 958651-46-2), molecular formula C11H16BrNO2S and molecular weight 306.22 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C11H16BrNO2S, 4-Bromo-N-tert-butyl-3-methylbenzenesulfonamide contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 306.22 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.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures 4-Bromo-N-tert-butyl-3-methylbenzenesulfonamide under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
