Chemical Structure
Description
Benzenesulfonamide, 4-bromo-N-1H-1,2,4-triazol-5-yl- (CAS 933241-34-0), molecular formula C8H7BrN4O2S and molecular weight 303.14 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Benzenesulfonamide, 4-bromo-N-1H-1,2,4-triazol-5-yl- (C8H7BrN4O2S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
CATO manufactures Benzenesulfonamide, 4-bromo-N-1H-1,2,4-triazol-5-yl- 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.
