Chemical Structure
Description
The occurrence of 4-Bromo-N-(4-bromo-3-fluorophenyl)benzenesulfonamide is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4-Bromo-N-(4-bromo-3-fluorophenyl)benzenesulfonamide (CAS 1024378-31-1), molecular formula C12H8Br2FNO2S and molecular weight 409.07 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-Bromo-N-(4-bromo-3-fluorophenyl)benzenesulfonamide (C12H8Br2FNO2S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/bromine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).
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.
As a certified reference material (CRM), 4-Bromo-N-(4-bromo-3-fluorophenyl)benzenesulfonamide meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
