ClassSmall Molecule
Description
2,3-Diethylpyrazine 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. 2,3-Diethylpyrazine is a moderately basic compound (based on its pKa). 2,3-Diethylpyrazine is a green, hazelnut, and nutty-tasting compound. Outside of the human body, 2,3-diethylpyrazine has been detected, but not quantified in a few different foods such as cereals and cereal products, nuts, and potato. It occurs naturally in asparagus, black or green tea, crispbread, malt, shrimp, soya, squid, Swiss cheeses, French fries, malt, peated malt, roasted barley, wild rice (Zizania aquatica), and wort. This could make 2,3-diethylpyrazine a potential biomarker for the consumption of these foods. 2,3-Diethylpyrazine is an alkylpyrazine. These are chemical compounds based on pyrazine with different substitution patterns and are formed during the cooking of some foods via Maillard reactions. 2,3-Diethylpyrazine is a flavour component in cooked foods (e.g. baked potato, wheat bread, and roasted filbert). 2,3-Diethylpyrazine is a flavouring ingredient, additive, and odorant in foods such as cereals and products such as cigarettes. 2,3-Diethylpyrazine is a component of the aroma of roasted sesame seeds.
