(E)-4-((4-(N-acetylsulfamoyl)phenyl)amino)-4-oxobut-2-enoic acid CAS 356567-68-5

Description

The occurrence of (E)-4-((4-(N-acetylsulfamoyl)phenyl)amino)-4-oxobut-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 (E)-4-((4-(N-acetylsulfamoyl)phenyl)amino)-4-oxobut-2-enoic acid (CAS 356567-68-5), a certified reference material (molecular formula C12H12N2O6S, MW 312.30 g/mol) for analytical method development and quality control.

(E)-4-((4-(N-acetylsulfamoyl)phenyl)amino)-4-oxobut-2-enoic acid (C12H12N2O6S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

CATO manufactures (E)-4-((4-(N-acetylsulfamoyl)phenyl)amino)-4-oxobut-2-enoic acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
