Opis

General description

4-Ethylguaiacol is a volatile compound, belonging to the class of phenols.[1] It is identified as one of the key aroma components in commercial soy sauce, red wine,[2] and apple cider.[1] The unpleasant smoky, spicy,[3] and clove-like aroma in wine is due to the presence of high concentrations of 4-Ethylguaiacol.[2]

Application

4-Ethylguaiacol may also be used as an analytical reference standard for the quantification of the analyte in the following:

• Commercial soy sauce using gas chromatography-olfactometry (GC-O).
• Red wine using gas chromatography-mass spectrometry (GC-MS).[2][3]
• Apple cider using gas chromatography-olfactometry (GC-O) and gas chromatography-mass spectrometry (GC-MS).[1]
