Metabolite Identification

Common Name

3,5-Dimethyl-2-(1-propenyl)pyrazine

Description

3,5-Dimethyl-2-(1-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. 3,5-Dimethyl-2-(1-propenyl)pyrazine has been detected, but not quantified in, several different foods, such as black tea, green tea, herbal tea, red tea, and teas (Camellia sinensis). This could make 3,5-dimethyl-2-(1-propenyl)pyrazine 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-(1-propenyl)pyrazine.
