Used as a key intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the development of fluorinated and brominated aromatic compounds. Its multiple halogen substituents allow selective cross-coupling reactions, making it valuable in medicinal chemistry for constructing complex molecules. Commonly employed in Suzuki, Stille, and Ullmann reactions to build biaryl structures found in bioactive compounds. Also utilized in the preparation of functional materials and ligands for catalysis due to its reactive halogen sites and phenolic functionality.
