4-Bromo-N-(3-chloro-4-methylphenyl)benzenesulfonamide CAS 349404-71-3

Description

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.

4-Bromo-N-(3-chloro-4-methylphenyl)benzenesulfonamide (CAS 349404-71-3) is a high-purity analytical reference standard with the molecular formula C13H11BrClNO2S and a molecular weight of 360.65 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine/bromine substitution, 4-Bromo-N-(3-chloro-4-methylphenyl)benzenesulfonamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 360.65 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

As a certified reference material (CRM), 4-Bromo-N-(3-chloro-4-methylphenyl)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.
