Compared with other compounds in its class, the molecular weight of 438.08 g/mol gives 4-Bromo-n-(2-iodophenyl)benzenesulfonamide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
4-Bromo-n-(2-iodophenyl)benzenesulfonamide (CAS 349404-93-9), molecular formula C12H9BrINO2S and molecular weight 438.08 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine/iodine substitution, 4-Bromo-n-(2-iodophenyl)benzenesulfonamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 438.08 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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-(2-iodophenyl)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.
