Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors for cancer treatment. Its iodine functionality allows for further cross-coupling reactions, enabling the construction of complex heterocyclic systems. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies due to its ability to enhance binding affinity and metabolic stability in target molecules. Also utilized in the preparation of labeled compounds for biochemical assays and imaging applications.
