Appearance

Pale straw-colored or very pale yellowish oily liquid.

Solubility

Insoluble in water, soluble in alcohol and oils.

Odor

Floral and fruity, rather heavy and powerful, Jasmin-like, warm and discretely spicy odor of moderate tenacity.

Uses in perfumery

This higher homologue of iso-Jasmone has been suggested for use in perfume compositions. Its tenacity is slightly superior, but its odor type not quite as desirable as the conventional iso-Jasmones. For novel Jasmin notes, for modifications of the pungent-floral theme in bases and finished fragrances, this ketone should have some future, if it were only made freely available.

Production

Produced by condensation of Cyclopentanone with Octanal (Aldehyde C-8).
