描述
2-vinylphenol is a member of the class of compounds known as styrenes. Styrenes are organic compounds containing an ethenylbenzene moiety. 2-vinylphenol is slightly soluble (in water) and a very weakly acidic compound (based on its pKa). 2-vinylphenol can be found in ceylon cinnamon and chinese cinnamon, which makes 2-vinylphenol a potential biomarker for the consumption of these food products. 2-vinylphenol is a phenolic compound found in wine and beer. It is produced by the spoilage yeast Brettanomyces. When it reaches concentrations greater than the sensory threshold, it can give the wine aromas described as barnyard, medicinal, band-aids, and mousy. In wine, 4-vinylphenol can react with other molecules, such as anthocyanidins, to produce new chemical compounds. In white wines vinylphenols are dominant (4-vinylphenol 70-1 150 μg/l, 4-vinylguajacol 10-490 μg/l) whereas, in red wines, it's the corresponding ethyl-phenols .
