Almost insoluble in water, soluble in alcohol, miscible with oils.
Warm, caramellic-herbaceous, mildly balsamic odor, in dilution almost floral in its balsam-notes.
The title ester is very rarely offered under its proper chemical name, but finds some use in perfume compositions as an undertone and occasionally as part of the less volatile base in a topnote composition. It will support herbaceous and balsamic-floral notes, Ylang, Labdanum, Rose, etc. and blends very well with Juniper berry oil notes in Ambre compositions.
Produced by azeotropic esterification of Tetrahydrofurfuryl alcohol with 2-Butenoic acid (alpha-Crotonic acid).
