(E)-4-((4-(N-(5-ethyl-1,3,4-thiadiazol-2-yl)sulfamoyl)phenyl)amino)-4-oxobut-2-enoic acid CAS 314282-44-5 chemical structure

Description

The occurrence of (E)-4-((4-(N-(5-ethyl-1,3,4-thiadiazol-2-yl)sulfamoyl)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.

(E)-4-((4-(N-(5-ethyl-1,3,4-thiadiazol-2-yl)sulfamoyl)phenyl)amino)-4-oxobut-2-enoic acid (CAS 314282-44-5), molecular formula C14H14N4O5S2 and molecular weight 382.41 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of (E)-4-((4-(N-(5-ethyl-1,3,4-thiadiazol-2-yl)sulfamoyl)phenyl)amino)-4-oxobut-2-enoic acid (C14H14N4O5S2) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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-(5-ethyl-1,3,4-thiadiazol-2-yl)sulfamoyl)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.
