Used as a key intermediate in the synthesis of fluorinated pharmaceuticals, particularly in the production of non-steroidal anti-inflammatory drugs (NSAIDs) and other bioactive molecules. Its aldehyde and ester functional groups allow for versatile chemical modifications, enabling the construction of complex aromatic structures. Commonly employed in cross-coupling reactions and condensation processes to introduce fluorinated aromatic moieties into drug candidates. Also utilized in the development of agrochemicals and specialty polymers where fluorine substitution enhances stability and reactivity.
