  • Applications

    Oct-6-enal (CAS 63826-25-5) is commonly used as an odorant in fragrance applications, providing a green, fresh aldehydic note that helps shape signature scents. Within cosmetics and personal care, it is used as a fragrance ingredient to contribute to the scent profile of lotions, shampoos, and similar products. In the food and flavor sector, it may serve as a flavor/aroma intermediate for certain formulations. In industrial manufacturing, Oct-6-enal is used as an intermediate to synthesize other aroma compounds. In household products and cleaners, it can be added as a fragrance component to impart scent.
