Used as a key intermediate in the synthesis of pharmaceutical agents, particularly in the development of kinase inhibitors for cancer therapy. Its structure supports selective binding to enzyme targets involved in cell signaling pathways. Commonly employed in research settings to design drugs targeting inflammatory diseases and certain solid tumors. Also utilized in medicinal chemistry for structure-activity relationship (SAR) studies due to its rigid, fused-ring framework that enhances metabolic stability and bioavailability in lead compounds.
