4-Ethylphenol is a volatile phenol. It has been synthesized from
p-coumaric acid by employing a synthetic medium containing
Dekkera bruxellensis ISA 1791. It has been identified as an aroma compound in red wine.
4-Ethylphenol (4-EP) is a
para-substituted phenolic compound. It is one of the important aroma compounds in red wine. The aroma associated with 4-EP in red wine has been described as horsy, leather, medicinal, smoky, barnyard, animal and sweaty saddle-like. Production of 4-EP from
p-coumaric acid in synthetic media utilizing several yeast species associated with wine production has been reported. Its electroactive center and oxidation pathways have been studied by voltammetric techniques at a glassy carbon electrode (GCE). Hydrogenolysis of lignin has been reported to form 3.1% of 4-EP. This method may be a potential alternative to the conventional petrochemical route of its synthesis. A sensor based on the molecularly imprinted nanoparticles to selectively detect 4-EP has been developed. The ability of polyaniline (PANI) materials and suberin extracted from cork in removing 4-EP from wine has been investigated.
4-Ethylphenol is suitable for use in the determination of 4-ethylguaiacol and 4-ethylphenol in the aroma of red wines using headspace-solid-phase microextraction method.
4-Ethylphenol may be used in the preparation of optically active 1-(4-hydroxyphenyl)- ethanol, via hydroxylation by
Pseudomonas putida and
p-cresol methylhydroxylase.
