Description and Uses
4-Ethyl pyridine is used as a monomer in polymer
chemistry.
4-Ethylpyridine could find use in perfume compositions since it gives very interesting effects with Vetiver, Oakmoss, Hydroquinone dimethylether, Amylsalicylate, Coumarin, Lavender, etc., and in minute traces in certain florals, e.g. Hyacinth and Tuberose, also for “bouquetting” purposes in floral fragrances describing flowers from the floor of the woods, Muguet, Violet, etc. where the sweet-earthy, fungal notes can be applied artistically with pleasant effect.
