Metabolite Identification

Common Name

2,5-Dimethyl-3-(2-propenyl)pyrazine

Description

2,5-Dimethyl-3-(2-propenyl)pyrazine 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. 2,5-Dimethyl-3-(2-propenyl)pyrazine has been detected, but not quantified in, potatos (Solanum tuberosum). This could make 2,5-dimethyl-3-(2-propenyl)pyrazine a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on 2,5-Dimethyl-3-(2-propenyl)pyrazine.
