The alpha-ionone is the alpha form of ionone. The ionones denote a series of chemical substances belonging to rose ketones including carotene, damascenes and damascenones. It is found in various kinds of essential oils contained in some flowers such as violet. Ionone has three forms including alpha-, beta and gamma-. The alpha-ionone has the aroma odor of violet, which has been widely used in daily chemical flavor and tobacco-used flavor. The alpha-ionone can be made from the thermal decomposition of carotene.

α-Ionone has a warm, woody, berry characteristic violet-like odor. The composition of commercial ionones varies
widely in the proportion of α- and β-isomers; the specifications given below refer to the best grade of α- and β-ionones and to a commercial grade that contains both α- and β-ionones.
| [Uses]
alpha-Ionone, is used in many floral accords. Gives a violet flower nuance to compositions, but is also used in rose, woody, amber, balsamic, and powdery fragrances. It is also used in perfumery, flavoring, and vitamin A (retinol) production for cosmetics and toiletries. beta isomer shows a less floral odor than the alpha. It has good substantivity and is used in all areas of perfumery. | [Uses]
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). | [Definition]
ChEBI: Alpha-ionone is an ionone, an enone and a methyl ketone. | [General Description]
α-lonone is a C13 norterpenoid formed from the degradation of carotenoids. It is an important fragrance compound used in perfume industries due to its characteristic fine violet and rose scents. Commercially α-lonone is used in cosmetics, personal care products, detergents, etc. As a flavoring agent, it is widely used in various beverages including wine and tea. | [Flammability and Explosibility]
Notclassified | [Purification Methods]
Purify α-ionone through a spinning band fractionating column. The semicarbazone has m 157-157.5o (from EtOH) and [] D +433o (c 4, |
