2,5-Diethyl-3,6-dimethylpyrazine

Description

2,5-Diethyl-3,6-dimethylpyrazine 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-Diethyl-3,6-dimethylpyrazine 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 2,5-diethyl-3,6-dimethylpyrazine a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on 2,5-Diethyl-3,6-dimethylpyrazine.
