Description2-Isopropyl-5-methylpyrazine 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 2-Isopropyl-5-methylpyrazine.
