Uses in perfumery :
Iralia® is used in floral notes of violet, carnation and in spicy tea notes. Often associated with Hedione®. Used in chypre notes for a different facet.
Natural availability :
Iralia® is not available in its natural state.
Year of discovery :
Iralia®' trademark has been published and protected by Firmenich SA since 07/11/1966 (brand N°325224)
Other comments :
Iralia® is more powdery than Ionones, but less fruity-sweet. Methyl Ionones are among the 26 allergens in perfumery.

Synthesis route :
The synthesis of Iralia® and methylionones is made from Citral and methyl ethyl ketone (instead of acetone for ionones). This synthesis step gives rise to two molecules called n-Methyl pseudoionone and Isomethyl pseudoionone, both having cis and trans diastereoisomers. The ratio of one molecule relative to the other is favoured by the choice of the reaction catalyst: the more alkaline the catalyst, the more Isomethyl pseudoionone will be favoured. For the cyclization step of Pseudoionone, as for conventional ionones, one isomer will be favoured depending on which acid is used.
Synthesis precursor :
Iralia® is not a precursor to the synthesis of another compound of olfactory interest.
Isomerism :
Iralia® is a mixture of molecules consisting mainly of alpha-isomethyl ionone, alpha-methyl ionone and a minority of beta-methyl ionone. All these molecules are isomers.
