Used primarily as an intermediate in organic synthesis, especially in pharmaceutical and agrochemical manufacturing. Its dual halogen functionality allows for selective cross-coupling reactions, making it valuable in the construction of complex aromatic compounds. Commonly employed in Suzuki, Stille, and Heck reactions to introduce aromatic rings into target molecules. Also utilized in the development of bioactive compounds, including drug candidates and functional materials, where precise halogen placement is required for further derivatization.
