Chemical Structure
Description
The occurrence of (Z)-4-Oxo-4-((4-(N-(thiazol-2-yl)sulfamoyl)phenyl)amino)but-2-enoic acid is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies (Z)-4-Oxo-4-((4-(N-(thiazol-2-yl)sulfamoyl)phenyl)amino)but-2-enoic acid (CAS 515-57-1), a certified reference material (molecular formula C13H11N3O5S2, MW 353.37 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, (Z)-4-Oxo-4-((4-(N-(thiazol-2-yl)sulfamoyl)phenyl)amino)but-2-enoic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 353.37 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
As a certified reference material (CRM), (Z)-4-Oxo-4-((4-(N-(thiazol-2-yl)sulfamoyl)phenyl)amino)but-2-enoic 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.
