  • Applications

    Dec-2-en-5-one, CAS 65570-25-4, is commonly used as a synthetic intermediate for aroma-related compounds and as an odorant/fragrance component in perfumery and cosmetics; it can function as an odorant or fragrance additive in personal care and consumer products with fragrance. In industry, it is viewed as an intermediate for the synthesis of other aroma chemicals and may serve as a building block for plastics, coatings, and related formulations with scent. It can also be used in household cleaning products as an odorant additive. Its exact applications depend on local regulations and formulation limits.
