Sweet and fruity, very tenacious, delicately Neroli-Orangeblossom-floral odor.
The taste in concentrations below 10 ppm is intensely fruity, sweet, of Strawberry-type.
This ether has found some use in perfume compositions, particularly as a fixative and undertone in Citrus colognes, inexpensive Neroli types, etc.
It is also used in flavor compositions — in countries where it is not prohibited — for imitation Strawberry and in various fruit complexes.
Produced by simple etherification of beta-Naphthol with a surplus of iso-Butanol under reflux in the presence of sulfuric acid. It has also been prepared from the sodium salt of beta-Naphthol with iso-Butylbromide.
