Used primarily as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors and other bioactive molecules. Its structure allows for selective functionalization, making it valuable in medicinal chemistry for constructing heterocyclic frameworks. Commonly employed in cross-coupling reactions such as Suzuki or Buchwald-Hartwig aminations to introduce aryl or amino groups. Also utilized in agrochemical research for designing novel active ingredients due to its electron-deficient aromatic system. Suitable for solid-phase and solution-phase combinatorial chemistry in drug discovery.
