Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of indole-based compounds with biological activity. Commonly applied in the preparation of kinase inhibitors and antitumor agents due to its ability to participate in cyclization and condensation reactions that form complex heterocyclic structures. Also utilized in agrochemical research for designing bioactive molecules with pesticidal or herbicidal properties. Its dual functional groups enable selective derivatization, making it valuable in combinatorial chemistry and drug discovery.
