Pale yellowish or straw-colored, or almost colorless oily liquid.
Insoluble in water, soluble in alcohol and oils.
Powerful and rich, powdery-velvety odor of considerable tenacity. Overall distinctly different from the odor of alpha-Methylionone and other common Methylionones.
Although this higher homologue is rarely, if ever, offered commercially under its proper chemical name, it has found some use in perfume compositions. Its unusually clean-powdery, lasting odor can be utilized by careful blending into novel luxury fragrances with macrocyclic musks or Indane-type musks, Ambregris chemicals, Clary Sage derivatives, Oakmoss products, Galbanum, etc. for modern type fragrances.
Produced by condensation of Citral with Methyl-iso-butylketone, followed by cyclization e.g. with Phosphoric acid.
