Chemistry & Uses
Uses in perfumery :
It can replace Methyl Octine or Methyl Heptine Carbonate, or be used as a new fresh green note.
A very stable and powerful green violet leaf note with a unique cucumber or bell pepper aspect.
Year of discovery :
1978 Brevet EP 0694604 registered in 1997 by Firmenich & CIE
Natural availability :
Violettyne is not available in its natural state
Isomerism :
1,3-undecadien-5-yne (Violettyne) is present as either one of its (E) or (Z) configuration isomers or as a mixture of the two. In the case of a mixture, the (E) form has to takes the majority.
Synthesis precursor :
Violettyne is a synthesis intermediary for galbanolene (1,3,5-undecatriene) and its isomers.
Synthesis route :
Full synthesis detailed here : https://doi.org/10.1002/hlca.19750580406
Stability :
Stable
Other comments :
The Violettyne is marketed while being diluted in the MIP, it is thus generally found under the name of "Violettyne MIP". This dilution ensures its stability and allows a better use (very strong intensity)
