Chemistry & Uses
Uses in perfumery :
Aldehyde C-11 Undecylenic provides an aldehydic facet in green, chypre, rose, floral-violet, tuberose notes. Used in detergents for its stability.
Year of discovery :
Data not available.
Natural availability :
Aldehyde C-11 Undecylenic has been identified as present in trace amounts in Coriander Leaf EO, but is not extracted in its natural state.
Isomerism :
Ethyl Linalool is a constitutional isomer of Aldehyde C-11 Undecylenic. Its smell is however much more floral-fresh and less zesty.
Synthesis precursor :
Aldehyde C-11 undecylenic forms a Schiff base by reaction with Methyl Anthranilate or Indole, for example. It can also be used for condensation with another aldehyde or ketone to form the desired alcene.
Synthesis route :
Like the other aliphatic aldehydes, Aldehyde C-11 undecylenic, can be synthesized by a reaction of undecylenyl halides (chloride, for example) with dimethyl sulfoxide (DMSO), followed by an alkaline treatment with sodium bicarbonate. Other synthetic routes exist, such as a reduction of Rosenmund from undecylenic acid, using an acid chloride.
Stability :
Aldehydes may form diethylacetals in alcoholic perfumes, with no real impact on their smell
Other comments :
Aldehyde C-11 Undecylenic is greener and less zesty-lemon than Aldehyde C-11 Undecylic. Aldehydes C-12 are more orange and less butyric. C-8 is less green.
