Used as a key intermediate in the synthesis of various pharmaceutical compounds, particularly in the development of active pharmaceutical ingredients (APIs) for therapeutic drugs. It plays a significant role in the production of molecules with potential anti-inflammatory, antiviral, or anticancer properties. Additionally, it is employed in organic synthesis to introduce fluorine atoms into aromatic systems, enhancing the biological activity and stability of target compounds. Its formyl group allows for further functionalization, making it valuable in creating complex chemical structures for drug discovery and development.
