Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) for central nervous system (CNS) drugs and antidepressants. It serves as a building block in the preparation of fluorinated organic compounds, where the fluorine atom enhances metabolic stability and bioavailability. Also employed in the manufacture of agrochemicals and specialty fine chemicals due to its reactivity and structural properties. Its aldehyde group allows for easy functionalization through condensation, reduction, or nucleophilic addition reactions, making it valuable in multi-step organic synthesis.
