Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors and antiviral agents. Its structure allows for selective functionalization, making it valuable in medicinal chemistry for creating potent bioactive molecules. Commonly employed in cross-coupling reactions such as Suzuki or Sonogashira to build complex heterocyclic systems. Also utilized in research settings for the design of new central nervous system (CNS) active drugs due to its ability to cross the blood-brain barrier.
