Chemical Information
FooDB Name3,5-Dimethyl-2-propylpyrazine
Description3,5-Dimethyl-2-propylpyrazine 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. 3,5-Dimethyl-2-propylpyrazine is a burnt and hazelnut tasting compound. 3,5-Dimethyl-2-propylpyrazine has been detected, but not quantified in, several different foods, such as cocoa and cocoa products, cocoa beans (Theobroma cacao), crustaceans, and nuts. This could make 3,5-dimethyl-2-propylpyrazine a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on 3,5-Dimethyl-2-propylpyrazine.
