Intense, tarry-animalic quinoline character with a leathery, tobacco-like facet and a whisper of orange-blossom floralcy in extreme dilution. In isolation it reads as harsh, phenolic and slightly fecal, but when heavily diluted it lends a warm, dry leather nuance reminiscent of the classical leather bases.AI · claude-opus-4-7

Pale yellowish or almost colorless liquid. Acquires a brownish color upon standing or exposure to daylight and air.

This Quinoline is used in perfume compositions as a fortifier of the heavy and intermediate notes where Tobacco-Civet-Honey-like fragrances are combined to heavy or exotic floral notes.
Produced from (many methods) e. g. from para-Toluidine and Glycerol by condensation under sulfuric acid conditions with an Iodine type catalyst.
