Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) where the cyclopropyl group enhances metabolic stability and binding affinity. It serves as a building block in the preparation of antiviral and anticancer agents. Also employed in the fragrance industry due to its aromatic character, contributing to the creation of complex scent profiles in perfumes and cosmetics. Its aldehyde functionality allows for easy modification in organic reactions, making it valuable in research and development of new chemical entities.
