Common Name | 2-Methyl-(3 or 5 or 6)-(methylthio)pyrazine (mixture of isomers) |
---|
Description | 2-Methyl-(3 or 5 or 6)-(methylthio)pyrazine (mixture of isomers) belongs to the class of organic compounds known as aryl thioethers. These are organosulfur compounds containing a thioether group that is substituted by an aryl group. 2-Methyl-(3 or 5 or 6)-(methylthio)pyrazine (mixture of isomers) is an almond, meat, and nutty tasting compound. 2-Methyl-(3 or 5 or 6)-(methylthio)pyrazine (mixture of isomers) has been detected, but not quantified in, a few different foods, such as arabica coffees (Coffea arabica), coffee and coffee products, and robusta coffees (Coffea canephora). This could make 2-methyl-(3 or 5 or 6)-(methylthio)pyrazine (mixture OF isomers) a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on 2-Methyl-(3 or 5 or 6)-(methylthio)pyrazine (mixture of isomers). |
