Chemical Information

FooDB Name

2,3-Diethyl-5-methylpyrazine

Description

2,3-Diethyl-5-methylpyrazine 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. 2,3-Diethyl-5-methylpyrazine is a citrus, earthy, and fatty tasting compound. 2,3-Diethyl-5-methylpyrazine has been detected, but not quantified in, several different foods, such as herbs and spices, milk and milk products, nuts, and potatos (Solanum tuberosum). This could make 2,3-diethyl-5-methylpyrazine a potential biomarker for the consumption of these foods. Based on a literature review a significant number of articles have been published on 2,3-Diethyl-5-methylpyrazine.
