2-Methoxy-3-methylpyrazine Usage And Synthesis
Chemical Properties2 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.
Chemical Propertiesclear colourless liquid
OccurrenceReported found in sherry and krill.
PreparationFrom 2-methylpyrazine by various routes.
DefinitionChEBI: 2-Methoxy-3-methylpyrazine is a member of pyrazines and an aromatic ether.
Aroma threshold valuesDetection: 3 to 7 ppb
