Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors and anti-cancer agents. Its structure supports the construction of complex heterocyclic systems found in bioactive molecules. Commonly employed in medicinal chemistry for scaffold modification and structure-activity relationship (SAR) studies due to its reactive functional groups, enabling easy derivatization. Also utilized in the preparation of indole-based analogs for drug discovery programs targeting inflammatory and neurological disorders.
