Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of indole-based drugs. It serves in the preparation of active pharmaceutical ingredients (APIs) for treatments related to inflammation, neurological disorders, and cancer. Its functional groups allow for easy modification in multi-step organic syntheses, making it valuable in medicinal chemistry research and drug discovery. Commonly employed in the production of selective enzyme inhibitors and receptor modulators due to the indole scaffold’s biological relevance.
