Application:

4-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.

Market News:The superiority to psilocybin is due in part to the incorporation of a conjugated amplification moiety (CAM) that enhances 5-HT2A specific effects while reducing non-specific effects.
