Used as a key intermediate in the synthesis of biologically active compounds, particularly in pharmaceuticals targeting central nervous system disorders. Its rigid fused ring structure makes it valuable in medicinal chemistry for developing potent and selective receptor modulators. Commonly employed in the preparation of kinase inhibitors and GPCR-targeted drugs due to its ability to enhance binding affinity and metabolic stability. Also explored in agrochemical research for designing novel pesticides with improved efficacy and environmental safety.
