Used as an intermediate in pharmaceutical synthesis, particularly in the development of bioactive molecules and drug candidates targeting neurological disorders and inflammation. Its indole core is valuable for constructing complex heterocyclic systems common in medicinal chemistry. The Boc-protected amine and carboxylic acid functional groups allow for selective reactions, enabling peptide coupling and sequential derivatization in multi-step syntheses. Commonly employed in the preparation of kinase inhibitors and serotonin receptor modulators. Also utilized in research settings for generating compound libraries in structure-activity relationship (SAR) studies.
