Chemical Structure

(E)-4-((4-(N-methyl-N-phenylsulfamoyl)phenyl)amino)-4-oxobut-2-enoic acid CAS 791793-63-0 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.

(E)-4-((4-(N-methyl-N-phenylsulfamoyl)phenyl)amino)-4-oxobut-2-enoic acid (CAS 791793-63-0) is a high-purity analytical reference standard with the molecular formula C17H16N2O5S and a molecular weight of 360.38 g/mol.

The molecular framework of (E)-4-((4-(N-methyl-N-phenylsulfamoyl)phenyl)amino)-4-oxobut-2-enoic acid (C17H16N2O5S) is characterized by a flavonoid core, 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).

CATO manufactures (E)-4-((4-(N-methyl-N-phenylsulfamoyl)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.
