Used in pharmaceutical research as a building block for the synthesis of complex molecules, particularly in the development of central nervous system (CNS) drugs. Its unique spirocyclic structure makes it valuable for creating compounds with potential therapeutic effects, such as antidepressants, antipsychotics, or analgesics. Additionally, it serves as a key intermediate in organic chemistry for exploring novel chemical reactions and pathways. Its application extends to drug discovery programs aiming to target specific receptors or enzymes in the body.
