Used as a key intermediate in the synthesis of fluorinated pharmaceuticals, particularly in the development of non-steroidal anti-inflammatory drugs (NSAIDs) and other bioactive molecules. Its structure allows for selective functionalization in drug design, enhancing metabolic stability and binding affinity. Commonly employed in cross-coupling reactions, such as Suzuki or Heck reactions, to build complex aromatic systems in medicinal chemistry. Also utilized in the preparation of radiolabeled compounds for imaging studies due to the presence of iodine, enabling tracking in biological systems.
