Common Name2-Ethyl-3,5-dimethylpyrazine
Description2-Ethyl-3,5-dimethylpyrazine, also known as 2,6-dimethyl-3-ethyl-pyrazine or FEMA 3150, or as 3,5-cocoa-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-Ethyl-3,5-dimethylpyrazine is a moderate base and a colorless to pale yellow clear liquid that is soluble in water and alcohol. It has a peanut-nutty, caramelly, coffee, musty, and roasted cocoa odor with a sweet, nutty, caramelly, coffee, corn, cocoa and potato taste. 2-Ethyl-3,5-dimethylpyrazine has been detected in roasted barley, chicory root, coffee, lavender oil from Spain (0.019%), roasted peanut, potato, rice cakes,  rum, tea leaf, whiskey (http://www.thegoodscentscompany.com/data/rw1008281.html#tooccur), fish, cereals and cereal products, tortilla chips, tea, and green vegetables. This could make 2-ethyl-3,5-dimethylpyrazine a potential biomarker for the consumption of these foods. It is a perfuming agent. 2-Ethyl-3,5-dimethylpyrazine is formed during the combustion of cannabis and is therefore a constituent of cannabis smoke ( Ref:DOI ).
