How it behaves

Olfactory profile

Descriptors
tobacco

Sharp, pungent secondary amine with a strong ammoniacal, fishy character reminiscent of trimethylamine. Not used as a fragrance ingredient in its own right — it is a reactive building block and its raw odor is harsh and repellent, though trace amine facets can suggest animalic or marine nuances.AI · claude-opus-4-7

Appearance

Almost colorless liquid.

Solubility

Miscible with water, alcohol and most oils.

Odor

Penetrating amine-type odor, reminiscent of ammonia and piperidine, nauseating and diffusive, of very poor tenacity.

Uses in perfumery

Although the title amine has been identified in tobacco leaves and carrot leaves, it has failed to find use in perfume and flavor compositions. Its volatility and repulsive odor make it difficult to use, even with strong fixation. Traces of the title material may be used in artificial flower absolutes and certain artificial essential oils, exotic flower bases, etc.

Production

Produced by hydrogenation of pyrrole with hydrogen iodide plus phosphorous, or with hydrogen in presence of Adams catalyst (platinic oxide).
