Appearance

Colorless mobile oil

Solubility

Practically insoluble in water, soluble in alcohol and oils

Odor

Very powerful oily-caramellic, 'baked-spicy' odor with citrusy undertones

Flavor

The title aldehyde could possibly be used in flavors, since it has much of the 'cooked' or even 'baked' fruit note, e.g. baked Apple, Orange, etc.

Uses in perfumery

It should have good possibilities in new topnote creations for perfumes of the citrusy, herbaceous and mildly fruity character

Production

Produced from Croton aldehyde and n-Heptanal by condensation. Also by double addition of Acetaldehyde to Heptanal
