Description and Uses

α-Ionone has a characteristic violet-like odor. α-Ionone may be prepared by condensing citral with acetone to form pseudoionone, which is then cyclized by acid-type reagents.

An aroma compound commonly found in essential oils such as rose oil. It is a degradation products of caratenoids produced by caratenoid cleavage dioxygenases (CCD).
