Used as a flavor and fragrance ingredient due to its fruity, floral, and slightly citrus-like odor. Commonly found in perfumery for creating fresh and green scent notes. Also employed in food flavorings to enhance fruity aromas, particularly in apple, strawberry, and plum-type flavors. Its conjugated diene structure makes it useful in organic synthesis, especially in Diels-Alder reactions for building cyclic compounds.
