Chemistry & Uses
Uses in perfumery :
Dynascone® is used in in all types of fragrances to give unique green, floral and fruity effects. It works very well for green notes such as cis-3-hexenol or galbanum but be careful, this raw material is very powerful and have an important volume. Very interesting for works around yellow fruits (bananas, pineapple) or for floral undertones in hyacinth, lilac ou lilly of the valley.

Dynascone® is not available naturaly
Isomerism :
Dynascone® may have two isomeric forms : Alpha-Dynascone® and Beta-Dynascone®. The alpha one is mainly used because of it is more green, powerful and linear.
Synthesis precursor :
Data not available.
Synthesis route :
Data not available.
Stability :
Very stable in all application
Other comments :
Very close to alpha-neobutenone® and Galbascone®
