Description
As a certified reference material (CRM), 2-((4-Carboxyphenyl)sulfonamido)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.
CATO supplies 2-((4-Carboxyphenyl)sulfonamido)benzoic acid (CAS 327092-89-7), a certified reference material (molecular formula C14H11NO6S, MW 321.31 g/mol) for analytical method development and quality control.
Structurally, 2-((4-Carboxyphenyl)sulfonamido)benzoic acid (C14H11NO6S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 321.31 g/mol, it falls into the moderately-high-molecular-weight range. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
