Used as a key 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 complex heterocyclic systems. Commonly employed in research settings to design drugs targeting cancer and inflammatory diseases due to its ability to modulate enzyme activity. Also utilized in the preparation of fluorescent probes and imaging agents, where its halogen atoms facilitate coupling reactions such as Suzuki or Buchwald-Hartwig aminations.
