Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 250.29 g/mol gives (E)-3-(3-ethoxy-4-isopropoxyphenyl)acrylic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
(E)-3-(3-ethoxy-4-isopropoxyphenyl)acrylic acid (CAS 932887-53-1) is a high-purity analytical reference standard with the molecular formula C14H18O4 and a molecular weight of 250.29 g/mol.
The molecular framework of (E)-3-(3-ethoxy-4-isopropoxyphenyl)acrylic acid (C14H18O4) 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).
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)-3-(3-ethoxy-4-isopropoxyphenyl)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.
