4-Bromo-2,5-difluorobenzenesulfonamide CAS 214209-98-0

Description

The occurrence of 4-Bromo-2,5-difluorobenzenesulfonamide is closely related to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 4-Bromo-2,5-difluorobenzenesulfonamide (CAS 214209-98-0), a certified reference material (molecular formula C6H4BrF2NO2S, MW 272.07 g/mol) for analytical method development and quality control.

4-Bromo-2,5-difluorobenzenesulfonamide (C6H4BrF2NO2S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/bromine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

As a certified reference material (CRM), 4-Bromo-2,5-difluorobenzenesulfonamide 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.
