Description

Compared with other compounds in its class, the molecular weight of 227.16 g/mol gives (E)-4-((2,4-difluorophenyl)amino)-4-oxobut-2-enoic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

(E)-4-((2,4-difluorophenyl)amino)-4-oxobut-2-enoic acid (CAS 1164538-71-9), molecular formula C10H7F2NO3 and molecular weight 227.16 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of (E)-4-((2,4-difluorophenyl)amino)-4-oxobut-2-enoic acid (C10H7F2NO3) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).

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-((2,4-difluorophenyl)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.
