Description

Compared with other compounds in its class, the molecular weight of 190.24 g/mol gives (Z)-4-((2,4-Dimethylphenyl)amino)-4-oxobut-2-enoic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

(Z)-4-((2,4-Dimethylphenyl)amino)-4-oxobut-2-enoic acid (CAS 7253-68-1), molecular formula C12H14O2 and molecular weight 190.24 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of (Z)-4-((2,4-Dimethylphenyl)amino)-4-oxobut-2-enoic acid (C12H14O2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. 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).

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-((2,4-Dimethylphenyl)amino)-4-oxobut-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.
