CITRONELLYL ISOBUTYRATE Usage And Synthesis

Chemical Properties

Rhodinyl isobutyrate has a fruity, sweet, floral odor with a fruity, floral, pineapple-like flavor, intensely sweet.

Occurrence

Has apparently not been reported to occur in nature.

Definition

ChEBI: Rhodinyl isobutyrate is a carboxylic ester.

Preparation

From rhodinol and isobutyric anhydride.

Metabolism

Open-chain olefinic terpene esters are presumably hydrolysed to the alcohol and the acid (Fassett, 1963). In the rabbit, the open-chain terpenes undergo ω-oxidation (Williams, 1959).
