Other names :
Decalactone-delta ; Amyl-delta-valerolactone ; Delta-amyl-valerolactone ; 5-decalactone ; Decan-5-olide ; Decano-1,5-lactone ; 5-decanolide ; 6-pentyltetrahydro-2H-pyran-2-one ; 6-pentyloxan-2-one
Uses in perfumery :
Delta-Decalactone is used for coconut reconstitutions, but also to bring a fruity and milky effect in sandalwood or fruity compositions for example.
Natural availability :
Delta-Decalactone is found in the odorous principle of many fruits as coconut, peach, raspberry, apricot and some cheeses. It does not exist on a natural state for perfumery.
Year of discovery :
Data not available.
Other comments :
Comparing with other lactones, Delta-Decalactone is without a doubt one of the most coconut-like one, with no real peach effect.
Price Range :
Lactones tend to polymerize through time, making them more viscous and leading to a phase shift in alcohol.

Synthesis route :
Delta-Decalactone can be prepared by oxidation of 2-pentylcyclopentanone, using a peracide.
Synthesis precursor :
Delta-Decalactone is not used for the synthesis of another compound used in perfumery.
Delta-Decalactone has one asymetric carbon. A mixture of its enantiomers is used for perfumery.
Delta-Decalactone is a constitutional isomer of Gamma-Decalactone, having one carbon atom less in its cycle, and one more in its ramified carbon chain. The resulting smell is very peachy for the isomer, and coconut-like for Delta-Decalactone.
