Used as a key intermediate in the synthesis of kinase inhibitors, particularly in pharmaceutical research targeting cancer therapies. Its structure supports the development of compounds that modulate enzyme activity involved in cell signaling pathways. It is also employed in the preparation of indole-based heterocyclic systems for drug discovery, offering potential in the design of antitumor and anti-inflammatory agents. Due to the presence of reactive functional groups, it facilitates coupling reactions and derivatization to generate compound libraries for biological screening.
