Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of central nervous system (CNS) agents. It serves as a building block for compounds exhibiting anticonvulsant, anxiolytic, and sedative properties. Its structure allows for functional modifications that enhance blood-brain barrier penetration, making it valuable in designing neuroactive drugs. Also employed in medicinal chemistry research for structure-activity relationship (SAR) studies due to its rigid heterocyclic core.
