Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors for cancer treatment. Its halogenated structure allows for selective cross-coupling reactions, enabling the construction of complex heterocyclic systems found in bioactive molecules. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies due to the distinct reactivity of bromo and iodo substituents, facilitating sequential functionalization. Also utilized in the preparation of fluorescent probes and materials for organic electronics where nitrogen-rich aromatic frameworks are required.
