Used as a key intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the development of kinase inhibitors and antitumor agents. Its iodine functionality allows for efficient coupling reactions, such as Suzuki or Heck reactions, enabling the construction of complex heterocyclic systems. Commonly employed in medicinal chemistry for lead optimization due to its ability to enhance binding affinity and metabolic stability. Also utilized in the preparation of pyrazole-based functional materials and as a building block in combinatorial chemistry.
