Chemical Structure
Description
The occurrence of n-(5-Bromopyrazin-2-yl)-2-chlorobenzenesulfonamide is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine/bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
n-(5-Bromopyrazin-2-yl)-2-chlorobenzenesulfonamide (CAS 1394691-91-8), molecular formula C10H7BrClN3O2S and molecular weight 348.60 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of n-(5-Bromopyrazin-2-yl)-2-chlorobenzenesulfonamide (C10H7BrClN3O2S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine/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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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 n-(5-Bromopyrazin-2-yl)-2-chlorobenzenesulfonamide 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.
