Used as a key intermediate in the synthesis of pharmaceutical agents, particularly in the development of kinase inhibitors and central nervous system (CNS) active compounds. Its scaffold is valued for enabling structural diversity in drug discovery, especially in optimizing potency and selectivity. Commonly employed in medicinal chemistry for building heterocyclic libraries aimed at targeting neurological disorders and inflammatory conditions. Also utilized in research settings to explore structure-activity relationships (SAR) due to its rigid, fused ring system that enhances binding interactions with biological targets.
