Appearance

Colorless mobile liquid.

Solubility

Almost insoluble in water, soluble in alcohol and oils, very poorly soluble in propylene glycol.

Odor

Powerful and diffusive, foliage-green odor, practically without trace of fatty or 'greasy' notes. However, the initial impression is that of a rather unnatural green, although it could be classified as a 'Lilac-green' type of odor.

Uses in perfumery

It offers interesting notes as a modifier in a complex of green odors, and blends very well with oakmoss and citrus oils.

Production

Produced from iso-Valeric aldehyde via 3-Methylbut-1-yne to the acid, from which subject ester is produced by conventional method.
