Appearance

Colorless liquid.

Solubility

Very slightly soluble in water, soluble in alcohol and oils.

Odor

Sweet, but faint, slightly fruity, pear-like odor, remotely reminiscent of terpene acetate or linalyl acetate, sweeter than the former, not as sweet as the latter.

Uses in perfumery

This acetal has been suggested for use in perfume compositions to assist in bringing citrusy (particularly bergamot-like) topnotes out and to give impression of sweet freshness.

Production

Produced from formaldehyde and iso-amyl alcohol. In place of formaldehyde, its dimethyl acetal may be used in the condensation.
