Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the production of selective serotonin reuptake inhibitors (SSRIs) and other central nervous system agents. Its structure allows for easy functionalization, making it valuable in creating fluorinated analogs of bioactive molecules. Commonly employed in medicinal chemistry for building blocks in drug discovery due to the enhanced metabolic stability and binding affinity provided by the fluorine atom. Also utilized in the preparation of agrochemicals and specialty organic compounds where fluorinated aromatic aldehydes are required.
