Used in organic synthesis as an intermediate for pharmaceuticals and bioactive compounds. Its structure supports the development of indole-based derivatives with potential applications in medicinal chemistry, particularly in the design of kinase inhibitors and antitumor agents. Commonly employed in cross-coupling reactions such as Suzuki or Heck reactions to build complex heterocyclic systems. Also utilized in the synthesis of fluorescent probes and optoelectronic materials due to its extended π-conjugated framework.
