Used as a key intermediate in the synthesis of fluorinated pharmaceuticals, particularly in the development of selective serotonin reuptake inhibitors (SSRIs) and other central nervous system agents. Its aldehyde and ether functionalities allow for versatile chemical modifications, making it valuable in constructing complex bioactive molecules. Commonly employed in condensation reactions, nucleophilic additions, and palladium-catalyzed couplings during drug discovery and process chemistry. Also utilized in the preparation of fluorescent probes due to its aromatic and electron-withdrawing characteristics.
