Solanone
From Wikipedia, the free encyclopedia
Solanone, also called 5-isopropyl-8-methyl-6,8-nonadien-2-one, is an unsaturated ketone, an organic chemical.[1] Its CAS number is [ ] and its SMILES structure is CC(CCC(C(C)C)/C=C/C(C)=C)=O.
It was discovered in 1967 by Johnson and Nicholson, American tobbaconists. It is naturally present in tobacco leaves. As the extraction of natural product is expensive, it is currently being mostly manufactured synthetically. It is also found in blackcurrant buds.
Solanone is used as a cigarette additive. It enhances the fragrance of tobacco, improving the sensoric qualities of cigarettes. It can also compensate the loss of flavor associated to procedures lowering tar content. [2]
