Used as a key intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the development of biologically active compounds. Its dual halogen functionality allows for selective cross-coupling reactions, making it valuable in constructing complex organic molecules. Commonly employed in Suzuki and Heck reactions to build aromatic frameworks found in drug candidates. Also utilized in the preparation of fluorescent dyes and optoelectronic materials due to its ability to serve as a building block for conjugated systems.
