Metabolite Identification

Common Name

3,5-Dimethyl-2-vinylpyrazine

Description

3,5-Dimethyl-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. 3,5-Dimethyl-2-vinylpyrazine is an earthy and musty tasting compound. 3,5-Dimethyl-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 3,5-dimethyl-2-vinylpyrazine 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-vinylpyrazine.
