Used as an intermediate in organic synthesis, particularly in cross-coupling reactions such as Suzuki and Heck reactions, to construct complex aromatic compounds. Its dual halogen functionality allows selective activation and substitution, making it valuable in pharmaceutical and agrochemical research for building substituted benzene derivatives. The methoxy group can act as a directing group or stabilize intermediates during metal-catalyzed transformations. Commonly employed in the development of functional materials and bioactive molecules.
