  • Applications

    15-Nonacosanone (CAS 2764-73-0) is a long-chain ketone widely used as a fragrance/odorant ingredient in perfumery and in cosmetics and personal care products, where its low volatility can contribute to scent profiles and fixation. It is also evaluated as a fragrance component in cosmetic formulations. In agriculture, the compound is studied and applied as a pheromone component for monitoring and trapping pest populations. In industrial manufacturing, it can serve as an intermediate for the synthesis of other long-chain ketones and related specialty chemicals used in polymer, lubricant, and coating formulations. Its use is subject to local regulations and formulation limits.
