Chemical Information
FooDB 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 fats and oils, coffee and coffee products, cocoa and cocoa products, green vegetables, and breakfast cereal. 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.
