Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) for central nervous system (CNS) drugs. It serves as a building block in the production of certain antivirals and psychotropic agents due to its ability to enhance blood-brain barrier penetration. Its structure supports the design of compounds with improved metabolic stability and receptor selectivity. Commonly employed in research and process chemistry for constructing complex heterocyclic systems in drug discovery programs.
