Chemical Information
FooDB Name5-methyl-5(H)-cyclopentapyrazine
Description5-Methyl-5H-cyclopenta[b]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. Based on a literature review very few articles have been published on 5-Methyl-5H-cyclopenta[b]pyrazine.
