Metabolite Identification
Common Name2-Methoxy-6-methylpyrazine
Description2-Methoxy-6-methylpyrazine belongs to the class of organic compounds known as methoxypyrazines. These are pyrazines containing a methoxyl group attached to the pyrazine ring. 2-Methoxy-6-methylpyrazine is an almond, hazelnut, and peanut tasting compound. 2-Methoxy-6-methylpyrazine has been detected, but not quantified in, alcoholic beverages. This could make 2-methoxy-6-methylpyrazine a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on 2-Methoxy-6-methylpyrazine.
