Used primarily as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of central nervous system (CNS) agents. Its structure allows for selective modifications, making it valuable in creating potent and selective ligands for neurological targets. It is often employed in the preparation of compounds with potential anxiolytic, antidepressant, or anticonvulsant activity. Due to its reactivity, it serves as a building block in medicinal chemistry for constructing complex heterocyclic systems found in drug candidates.
