Description2-Ethyl-3,5-dimethylpyrazine, also known as 2,6-dimethyl-3-ethyl-pyrazine or fema 3150, 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-Ethyl-3,5-dimethylpyrazine is a moderately basic compound (based on its pKa).
