Used as a key intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the development of bioactive molecules with pyrazole scaffolds. Its iodine functionality allows for further transformations via cross-coupling reactions such as Suzuki or Heck couplings, enabling the construction of complex heterocyclic systems. Commonly employed in medicinal chemistry for the preparation of kinase inhibitors and other targeted therapies. Also utilized in the design of functional materials and ligands for catalysis due to its reactive aldehyde and halogen groups.
