4-Bromo-2-fluoro-N-(4-iodophenyl)-benzenesulfonamide CAS 1771023-28-9

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-Bromo-2-fluoro-N-(4-iodophenyl)-benzenesulfonamide.

4-Bromo-2-fluoro-N-(4-iodophenyl)-benzenesulfonamide (CAS 1771023-28-9) is a high-purity analytical reference standard with the molecular formula C12H8BrFINO2S and a molecular weight of 456.07 g/mol.

Based on its molecular formula C12H8BrFINO2S, 4-Bromo-2-fluoro-N-(4-iodophenyl)-benzenesulfonamide contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/bromine/iodine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 456.07 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
