2-Methoxy-3-methylpyrazine Usage And Synthesis

Chemical Properties

clear colourless liquid

Chemical Properties

2 or 5 or 6-Methoxy-3-methylpyrazine has an aroma reminiscent of hazelnut, almond and peanut. The methyl methoxy pyrazines are used as nut-like flavoring agents for foods and beverages. The 2-methoxy-3-methyl derivative is used as a coffee aroma enhancing agent.

Occurrence

Reported found in sherry and krill.

Preparation

From 2-methylpyrazine by various routes.

Definition

ChEBI: 2-Methoxy-3-methylpyrazine is a member of pyrazines and an aromatic ether.

Aroma threshold values

Detection: 3 to 7 ppb
