An intensely animalic, fecal-leathery aromachemical with a narcotic floral undertone reminiscent of overripe jasmine and civet. In extreme dilution it lends a warm, skin-like radiance and leather nuance; neat it is repulsively barnyard and horse-stable. Signature use is trace-dosing to add carnal depth to florals and leather accords.AI · claude-opus-4-7

Colorless or pale amber-colored, needle-like crystals.
Slightly soluble in water, soluble in alcohol and oils.
Very powerful and tenacious, sweet-animal odor with honey-like undertone. Floral notes are perceptible upon extreme dilution of the material, but the undiluted quinoline has a rather unpleasant, civet-like odor.
This material is one of the most frequently used quinoline derivatives in perfumery. It is used in artificial civet or civet bases, as a fixative in floral, balsamic, Oriental or Ambre-like fragrances, and in honey or tabac bases. It is almost a standard ingredient, although always in discrete proportions. It also blends well with Amylcinnamic aldehyde for variations in the Jasmin theme, Tuberose, Gardenia and many other heavy or exotic florals. With Phenylacetic acid, Opopanax, Sandalwood and Cinnamates, it may contribute fixation and background for Oriental fragrances.
Produced from 6-Methylquinoline hydrochloride by reduction with nascent hydrogen, followed by neutralization. Also with hydrogen and a nickel catalyst. The methylquinoline is usually obtained by a Skraup’s synthesis.
