Used in pharmaceutical research as a key intermediate in the synthesis of biologically active compounds, particularly in the development of kinase inhibitors and central nervous system agents. Its structure supports the design of molecules with high binding affinity to specific enzyme targets. Commonly employed in medicinal chemistry for optimizing drug candidates due to its rigid, fused heterocyclic framework that enhances metabolic stability and selectivity. Also utilized in the preparation of novel receptor modulators for treating neurological disorders and inflammatory conditions.
