Chemistry, Properties & Perfumer Guide
The Chemistry
1,3-Dimethyl-3-butenyl salicylate belongs to the salicylate ester class, synthesized through esterification of salicylic acid with 1,3-dimethyl-3-butenol. The branched olefinic structure contributes to its volatility profile and green character. Unlike simpler salicylates, this molecule’s tertiary carbon and double bond create unique steric effects that modify its odor properties and substantivity.
