OccurrenceReported found in bakery products, cocoa products, coffee, meat, peanuts, filberts, potato products, beer, whiskey, tea, soybeans, rice, roasted coconut, corn tortillas, shrimp, crayfish, asparagus, boiled beef, malt whiskey, and malt
UsesEthylpyrazine has been used in the synthesis of pyrazinoic acid.
UsesEthylpyrazine is a reagent used in the synthetic preparation of various pharmaceutical goods and has been screened for potential activities as H1-antihistamine.
DefinitionChEBI: A member of the class of pyrazines that is pyrazine in which one of the hydrogens is replaced by an ethyl group. Found particularly in cereals and cereal products, it is present in baked or fried potato, bread, roasted peanuts, and cooked shrimp, as well a cocoa, coffee, and tea. It has a musty, nutty, buttery, peanut odor and a chocolate-peanut taste.
