2-METHYL-1-UNDECANOL Chemical Properties,Usage,Production

Chemical Properties

Colorless oily liquid, solidifying in the cold. Almost insoluble in water, soluble in alcohol and oils.

Uses

2-methyl undecanol is occasionally used in perfume compositions, mainly as a blender/ modifier in delicate floral fragrance types (Lily, Rose, Peony, Freesia, etc.). It does not contribute much odor, but its natural-waxy effect is appreciated in those rare cases.

Preparation

2-methyl undecanol is produced from Methyl nonyl acetaldehyde by hydrogenation.
