  • Applications

    5,9,13-Pentadecatrien-2-one, 6,10,14-trimethyl- (CAS 762-29-8) is primarily used as an aroma/fragrance ingredient and can function as an intermediate in the synthesis of odor compounds. In real-world applications, it is commonly considered for perfumery and cosmetics/personal care where it contributes to fragrance profiles; it may also be used in household products such as air fresheners and cleaners to impart a scent; it could be evaluated for flavor/aroma formulations in food-related applications at the development stage; and as an intermediate in industrial fragrance manufacturing, it supports downstream synthesis of related aroma chemicals.
