Dimethylionone is extremely versatile in character, and effects ranging from sweet floral to tobacco-like or woody are obtainable with various grades of subject material. 
The most refined grades, which are quite expensive, often show a very attractive ‘creamy’ top-note and a most uniform, powdery-sweet dryout performance. 

This type of Dimethylionone can support floral notes in Ylang-Ylang as well as woody notes in Vetiver, or leathery notes in Salicylates, etc.
Certain types of perfume contain up to 25% or more of this material. 

Many soap perfumes are based upon a large volume of common-grade Dimethylionone with the subject isomer as pre-dominant component.”
Dimethylionone is yellow transparent liquid with woody and floral odor.

Dimethylionone was synthesized by condensation of citral and butanone under alkaline conditions and then through the cyclization reaction to produce Dimethylionone.
Dimethylionone is mainly used in the flavor formulation of food and beverage.
