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 substitution reactions, making it valuable in constructing complex aromatic compounds. Commonly employed in cross-coupling reactions such as Suzuki or Heck reactions to form carbon-carbon bonds in drug discovery. Also utilized in the preparation of chiral building blocks for asymmetric synthesis, enhancing the efficiency of producing enantiomerically pure drugs.
