2-(4-Bromobenzenesulfonamido)benzoic acid CAS 51012-29-4

Description

As a certified reference material (CRM), 2-(4-Bromobenzenesulfonamido)benzoic acid 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.

2-(4-Bromobenzenesulfonamido)benzoic acid (CAS 51012-29-4), molecular formula C13H10BrNO4S and molecular weight 356.19 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C13H10BrNO4S, 2-(4-Bromobenzenesulfonamido)benzoic acid contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 356.19 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
