Uses

Ethylpyrazine has been used in the synthesis of pyrazinoic acid.

Uses

Ethylpyrazine is a reagent used in the synthetic preparation of various pharmaceutical goods and has been screened for potential activities as H1-antihistamine.

Definition

ChEBI: 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.
