1-Bromo-4-((4-nitrophenyl)sulfonyl)benzene CAS 75124-91-3

Description

The occurrence of 1-Bromo-4-((4-nitrophenyl)sulfonyl)benzene is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1-Bromo-4-((4-nitrophenyl)sulfonyl)benzene (CAS 75124-91-3), molecular formula C12H8BrNO4S and molecular weight 342.17 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 substitution, 1-Bromo-4-((4-nitrophenyl)sulfonyl)benzene is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 342.17 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), 1-Bromo-4-((4-nitrophenyl)sulfonyl)benzene 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.
