Appearance

Almost colorless oily liquid

Odor

Fresh-green, spicy-herbaceous Cassia-cinnamon type odor, more Cassia-like than the Diethyl acetal, yet less harsh than the aldehyde

Flavor

May introduce Cinnamon type odor when used at a sufficiently high level of concentration.

Uses in perfumery

Used as a lasting top note ingredient in many types of "modern" fragrances, not only in copies of successful French perfumes, but also in general as a novelty along with aldehydic-floral or Oriental-spicy or sweet-woody fragrance types. It forms interesting top notes with alifatic aldehydes in Rose-Jasmin fragrances, and gives pleasant variations of woody-oakmoss types.

Production

By condensation of Cinnamic aldehyde with Methanol
