Uses
Uses in perfumery :
2-ethyl-3-methyl Pyrazine si useful for reconstitutions of coffee, chocolate, hazelnut and other cooked and grilled food notes.
Year of discovery :
Data not available.
Natural availability :
2-ethyl-3-methyl Pyrazine is not available in its natural state.
Isomerism :
2-ethyl-3-methyl Pyrazine has no known isomer in perfumery.
Synthesis precursor :
2-ethyl-3-methyl Pyrazine is not a precursor to the synthesis of another compound of olfactory interest.
Synthesis route :
2-ethyl-3-methyl Pyrazine is part of a family of molecules which scent is close to peanuts as well as cooked and roasted fruits. Pyrazines are often obtained with a Gutknecht or Gastaldi condensation reaction, in both cases to condense two amines on two ketones, under the effect of an acid and oxidation. Here, one of the reagents contains the methyl and ethyl groups of the final molecule, while the other does not have any branches.
