Chemical Information
FooDB Name3-Ethyl-5-methyl-2-vinylpyrazine
Description3-Ethyl-5-methyl-2-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. 3-Ethyl-5-methyl-2-vinylpyrazine is an earthy tasting compound. 3-Ethyl-5-methyl-2-vinylpyrazine 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 3-ethyl-5-methyl-2-vinylpyrazine a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on 3-Ethyl-5-methyl-2-vinylpyrazine.
