Used as a key intermediate in organic synthesis, particularly in the production of pharmaceuticals and agrochemicals. Its unique halogen substitution pattern allows for selective functionalization, including nucleophilic substitutions, making it valuable in the development of complex molecules. It is also employed in cross-coupling reactions, such as Suzuki and Sonogashira couplings, to create aromatic compounds with specific properties. Additionally, it serves as a building block in materials science for designing advanced polymers and liquid crystals.
