  • Applications

    Primarily used as a fragrance ingredient and a synthetic intermediate in flavor and fragrance chemistry; it serves as a building block for aroma compounds and can function as a reactive intermediate in downstream synthesis. In perfumery, it contributes to green and citrus-like notes owing to its conjugated diene–alcohol structure. It is also encountered in cosmetics and personal care formulations as an odor component, and in household products such as cleaners and air fresheners to impart scent. Additionally, it may be used as a precursor in polymer, coatings, and ink formulations where a fragrance note is desired.
