Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and antiviral agents. Its structure allows for selective functionalization, making it valuable in creating biologically active molecules. Commonly employed in medicinal chemistry for building blocks in drug discovery programs targeting oncology and infectious diseases. Also utilized in the preparation of labeled compounds for research and diagnostic applications due to the presence of iodine, which facilitates radiolabeling or imaging studies.
