Used in the fragrance industry as a flavor and aroma compound due to its strong, fresh, and citrus-like odor. It serves as a key intermediate in the synthesis of complex perfumes, particularly those mimicking green, fruity, or floral notes. Its conjugated dienal structure provides stability and reactivity useful in organic synthesis for creating more complex scent molecules. Also employed in research settings to study conjugated systems and their reactivity in aldol and Michael addition reactions.
