2-Methoxypyrazine Usage And Synthesis
Description2-methoxypyrazine is a kind of pyrazine derivative. It emits a kernels and cocoa-like aroma. It is a commonly used daily, food flavoring agent. It has many kinds of flavoring derivatives such as 3-Isobutyl-2-methoxypyrazine, 3-sec-butyl-2-methoxypyrazine, 3-alkyl-2-methoxypyrazines and 3-isopropyl-2-methoxypyrazine. There derivatives could be found in wine and many kinds of fruits such as berry and grapes.

DescriptionMethoxypyrazine has an odor threshold of 700 ppb in water. Methoxypyrazine may be prepared from 2-hydroxypyrazine by various routes.
Chemical PropertiesColorless liquid
Chemical PropertiesMethoxypyrazine has a sweet, nutty, cocoa odor. Methoxypyrazine contributes a distinctive “green, capsicum (bell pepper), herbaceous and earthy” aroma that is quite characteristic of certain wines, such as sauvignon blanc and cabernet sauvignon.
OccurrencePresent at ultra-trace levels in sauvignon blanc and cabernet sauvignon grapes and wine. Methoxypyrazine contributes a distinctive wine aroma, even at low parts per trillion levels. Also reported found in cooked beef, cocoa, malt and krill.
PreparationFrom 2-hydroxypyrazine by various routes.
DefinitionChEBI: Methoxypyrazine is an aromatic ether and a member of pyrazines.
Aroma threshold values700 ppb in water
Safety ProfileSkin and eye irritant. When heated to decomposition it emits toxic fumes of NOx.
