Chemical Information
FooDB Name6,7-Dihydro-2,5-dimethyl-5H-cyclopentapyrazine
Description6,7-Dihydro-2,5-dimethyl-5H-cyclopentapyrazine 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. 6,7-Dihydro-2,5-dimethyl-5H-cyclopentapyrazine is a burnt, earthy, and nutty tasting compound. 6,7-Dihydro-2,5-dimethyl-5H-cyclopentapyrazine has been detected, but not quantified in, several different foods, such as cocoa and cocoa products, robusta coffees (Coffea canephora), breakfast cereal, arabica coffees (Coffea arabica), and coffee and coffee products. This could make 6,7-dihydro-2,5-dimethyl-5H-cyclopentapyrazine a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on 6,7-Dihydro-2,5-dimethyl-5H-cyclopentapyrazine.
