Used in organic synthesis as an intermediate for pharmaceuticals and biologically active compounds. Its fused heterocyclic structure makes it valuable in developing drug candidates, particularly in neuroscience and medicinal chemistry research. Commonly employed in the preparation of pyrrole-fused derivatives with potential neurological or anti-inflammatory activity. Also utilized in the design of novel ester-based prodrugs due to its favorable metabolic profile and ability to enhance bioavailability. Serves as a building block in combinatorial chemistry for high-throughput screening libraries targeting central nervous system receptors.
