Head
Uses in perfumery :
Galbazine is used in green notes of tomato leaf or violet leaf, in orange blossom notes and woody-patchouli accords.
Natural availability :
Galbazine is found in traces in Galbanum EO for example, and can be extracted from it. In the majority of cases, synthetic Galbazine remains the most used.
Year of discovery :
1969
Other comments :
In comparision to 2-methoxy-3-isopropyl Pyrazine, Galbazine has a much more fruity note, linked to its raw vegetables note. For this facet, Galbazine is more used in perfumes.

Synthesis route :
Galbazine is a molecule of the Pyrazine family. Pyrazines are often obtained by a condensation reaction of Gutknecht or Gastaldi, aiming in both cases to condense two amines on two ketones, under the effect of an acid and oxidation. Here, one of the reagents contains an isobutyl group and a methoxy group of the final molecule, while the other does not have any branches.
Synthesis precursor :
Galbazine is not a precursor to the synthesis of another compound of olfactory interest.
Isomerism :
Galbazine does not have any isomer used in perfumery.
