Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and antiviral agents. Its functionalized aromatic structure allows for selective modifications, making it valuable in medicinal chemistry for constructing complex drug molecules. Commonly employed in cross-coupling reactions and nucleophilic substitutions to introduce the substituted phenyl ring into larger bioactive structures. Also utilized in the preparation of agrochemicals and specialty materials where halogenated building blocks are required.
