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 functionalization, making it valuable in constructing complex heterocyclic systems found in bioactive molecules. Commonly employed in cross-coupling reactions such as Suzuki or Buchwald-Hartwig to introduce aryl or amino groups, enabling the optimization of drug candidates targeting neurological disorders and inflammatory diseases. Also utilized in materials science for designing organic semiconductors due to its electron-rich framework.
