Chemical Structure
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.
2-{[4-(methylsulfamoyl)phenyl]sulfanyl}benzoic acid (CAS 1155567-20-6), molecular formula C14H13NO4S2 and molecular weight 323.39 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-{[4-(methylsulfamoyl)phenyl]sulfanyl}benzoic acid (C14H13NO4S2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
As a certified reference material (CRM), 2-{[4-(methylsulfamoyl)phenyl]sulfanyl}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.
