Used in fragrance formulations for its fresh, citrusy, and slightly green aroma. Commonly found in perfumes, soaps, and household cleaners to enhance scent profiles. Its volatile nature makes it suitable for top notes in perfumery, providing an initial burst of freshness. Also employed in flavor compositions to impart a fruity nuance in low concentrations. Reacts readily due to the aldehyde and alkene functional groups, making it a building block in organic synthesis for more complex aroma chemicals.
