Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors for cancer treatment. Its structure allows for selective modification in drug design, enhancing binding affinity to target proteins. Commonly employed in cross-coupling reactions, such as Suzuki or Heck reactions, to introduce aryl or heteroaryl groups during the construction of bioactive molecules. Also utilized in the preparation of labeled compounds for use in radiopharmaceutical research and imaging studies.
