Metabolite Identification
Common Name2-Methyl-5-vinylpyrazine
Description2-Methyl-5-vinylpyrazine belongs to the class of organic compounds known as pyrazines. Pyrazines are compounds containing a pyrazine ring, which is a six-member aromatic heterocycle, that consists of two nitrogen atoms (at positions 1 and 4) and four carbon atoms. 2-Methyl-5-vinylpyrazine is a coffee tasting compound. 2-Methyl-5-vinylpyrazine has been detected, but not quantified in, several different foods, such as arabica coffees (Coffea arabica), green vegetables, potatos (Solanum tuberosum), breakfast cereal, and cocoa beans (Theobroma cacao). This could make 2-methyl-5-vinylpyrazine a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on 2-Methyl-5-vinylpyrazine.
