Common Name2-Ethyl-3-methylpyrazine
Description2-Ethyl-3-methylpyrazine, 9CI, also known as FEMA 3155 or filbert pyrazine, 3-ethyl-2-methyl, 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-methylpyrazine, 9CI is a moderately basic, colorless to pale yellow clear liquid. 2-Ethyl-3-methylpyrazine, 9CI has a nutty, peanut, musty, corn raw-earthy bready odor and a nutty, peanut, musty, corn, raw oily taste. 2-Ethyl-3-methylpyrazine, 9CI has been detected in filberts, peanuts, shrimp, coffee, cocoa, roasted barley, cooked beef, cereals and cereal products, eggs, fenugreek seed, potato products, tortilla chips and soy products ( Ref:DOI ). This could make 2-ethyl-3-methylpyrazine, 9CI a potential biomarker for the consumption of these foods. 2-Ethyl-3-methylpyrazine is also a constituent of cannabis smoke. It is formed during the combustion of cannabis ( Ref:DOI ).
