Chemical Structure

3-(2,3,4-Trimethoxyphenyl)acrylic acid CAS 33130-03-9 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 238.24 g/mol gives 3-(2,3,4-Trimethoxyphenyl)acrylic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

3-(2,3,4-Trimethoxyphenyl)acrylic acid (CAS 33130-03-9), molecular formula C12H14O5 and molecular weight 238.24 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 3-(2,3,4-Trimethoxyphenyl)acrylic acid (C12H14O5) 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).

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 3-(2,3,4-Trimethoxyphenyl)acrylic 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.
