  • Applications

    4-Methyl-2-pentylpyridine (CAS 84625-54-7) is primarily used as an odorant and fragrance ingredient in perfumery, contributing distinctive woody or green notes. It may be used in cosmetics and personal care products to impart fragrance, and in household products such as air fresheners and cleaners for scent enhancement. In industrial manufacturing, it can serve as an intermediate in fragrance chemistry and related syntheses. It may also be employed as a fragrance additive in coatings and inks to provide scent release in finished products.
