Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors for cancer treatment. Its structure allows for selective modification, making it valuable in medicinal chemistry for creating targeted therapies. Commonly employed in cross-coupling reactions such as Suzuki or Buchwald-Hartwig to build complex drug-like molecules. Also utilized in the preparation of radiolabeled compounds for use in positron emission tomography (PET) imaging due to the presence of iodine, enabling diagnostic applications in oncology and neurology.
