Chemistry & Uses
Uses in perfumery :
Used to bring creamy facets to reconstituted vanilla, coconut or gardenia.
Year of discovery :
Data not available.
Natural availability :
Data not available.
Isomerism :
Delta-Undecalactone has an asymetric carbon. Nevertheless, we always use its racemic mixture in perfumery. Delta-Undecalactone is an isomer of C14 Aldehyde, which has one less carbon atom into its ring, but one more in its ramified carbon chain. The resulting odor changes from a metallic peach and coconut odor to a fruity peach odor
Synthesis precursor :
Delta-Undecalactone is not a precursor to the synthesis of another compound of olfactory interest.
Synthesis route :
Delta-Undecalactone can be synthesized by an oxidation reaction of 2-hexylcyclopentanone, using a peracid.
Stability :
Lactones tend to polymerize through time, making them more viscous and leading to a phase shift in alcohol.
Other comments :
Data not available.
