Chemical Information
FooDB Name2-Methyl-3-(2-methylpropyl)pyrazine
Description2-Methyl-3-(2-methylpropyl)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-Methyl-3-(2-methylpropyl)pyrazine is a green, herbal, and sugar tasting compound. 2-Methyl-3-(2-methylpropyl)pyrazine has been detected, but not quantified in, several different foods, such as arabica coffees (Coffea arabica), coffee and coffee products, potatos (Solanum tuberosum), robusta coffees (Coffea canephora), and root vegetables. This could make 2-methyl-3-(2-methylpropyl)pyrazine a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on 2-Methyl-3-(2-methylpropyl)pyrazine.
