Beta-Naphthol propyl ether (Nerolin Yara Yara's propyl homologue) has a sweet, clean orange-blossom / neroli-like floral character with a slightly powdery, soapy facet. Less intense and more refined than the methyl ether (Yara Yara), with a softer, more diffusive white-floral quality reminiscent of neroli and petitgrain.AI · claude-opus-4-7

Colorless needlelike crystals.
Insoluble in water, soluble (about 8%) in cold alcohol, better in hot alcohol and in most perfume oils.
Very sweet and delicate fruity-floral odor of excellent tenacity. The floral notes are discretely neroli-like, while the fruity notes have a remote resemblance to Strawberry.
This ether, very rarely offered commercially, has found a little use in perfume compositions for its persistent odor and intense sweetness. It can be produced at a very attractive cost, and it is stable in soaps or against heat. With Hydroquinone dimethylether in Hyacinth compositions, or with Ethyl methyl phenyl glycidate in Rose variations, it may give very interesting results.
Produced from n-Propylalcohol (in surplus) with beta-Naphthol and sulfuric acid, by refluxing for 6 hours.
