Chemistry & Uses
Uses in perfumery :
Jasmonal A® is useful for light floral accords such as spring and white flowers : jasmine, lilac, tuberose or narcissus notes. Also used in fruity notes.
Year of discovery :
1926
Natural availability :
Jasmonal A® is found in trace amounts in some black teas. However, it is synthetic Jasmonal A® that is most often used in perfumery.
Isomerism :
Jasmonal A® has a double bond that gives rise to two possible diastereoisomers of the molecule. However, it is the mixture of the two diastereoisomers that is used in perfumery.
Synthesis precursor :
Jasmonal A® is not a precursor to the synthesis of another compound of olfactory interest.
Synthesis route :
As for Cinnamaldehyde, the synthesis of Jasmonal A® is made by a condensation of Benzaldehyde with heptanal (Aldehyde C-7), using an excess of Benzaldehyde and gradually adding the Aldehyde C-7 in order to avoid it self-condensation.
Stability :
Aldehydes may form diethylacetals in alcoholic perfumes, with no real impact on their smell.
Jamsonal A colors through time.
Other comments :
Jasmonal A® is more powerful, rising and soapy, but less watery than Jasmonal H®.
Jasmonal A® is one of the 26 allergens in perfumery.
