General description
4-Methoxyphenylacetic acid belongs to the class of aryl alkanoic acids, with a broad-spectrum of applications, which includes its role as an intermediate in synthetic organic chemistry, building block material for the production of a variety of essential drugs, an additive in the manufacture of unsubstituted indigo dyes and corrosion inhibitor for aluminum in acidic and alkaline solutions. It is a structural analog of 2-(4-methoxyphenoxy)propanoic acid, reported to occur in cocoa products.
Application
4-Methoxyphenylacetic acid may be used as an analytical reference standard for the determination of the analyte in Illicium verum Hook. f. using gas chromatography coupled to mass spectrometry (GC-MS) technique and urine samples using high-performance liquid chromatography (HPLC) with ultraviolet and fluorescence detectors.
