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 potency and specificity. Commonly employed in cross-coupling reactions, such as Suzuki or Heck reactions, to introduce aromatic or heteroaromatic groups. Also utilized in the preparation of fluorescent probes and bioactive molecules targeting neurological disorders due to its affinity for central nervous system receptors.
