Chemical Structure

4-(3,4-Dimethoxyphenyl)-4-oxobut-2-enoic acid CAS 57045-33-7 chemical structure

Description

The occurrence of 4-(3,4-Dimethoxyphenyl)-4-oxobut-2-enoic acid is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 4-(3,4-Dimethoxyphenyl)-4-oxobut-2-enoic acid (CAS 57045-33-7), a certified reference material (molecular formula C12H12O5, MW 236.22 g/mol) for analytical method development and quality control.

The molecular framework of 4-(3,4-Dimethoxyphenyl)-4-oxobut-2-enoic acid (C12H12O5) 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 the polarity and ionization state of its functional groups, 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), 4-(3,4-Dimethoxyphenyl)-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.
