The aldehyde itself has very little to offer to the creative perfumer, but it opens the door for the perfume chemist to make Tetrahydrofarnesal or Nor-hexahydrofarnesal, two very interesting floral perfume materials.
1) Farnesal is produced from Cabreuva oil, from which Nerolidol is isolated by distillation. Oxidation with CrO yields Farnesal. 2) From synthetic Nerolidol (Roche process).
