Used in pharmaceutical research as a building block for synthesizing complex molecules, particularly in the development of central nervous system (CNS) drugs. Its spirocyclic structure makes it valuable for creating compounds with potential therapeutic effects, such as antidepressants or anxiolytics. Additionally, it serves as an intermediate in organic synthesis, enabling the production of novel chemical entities for drug discovery and medicinal chemistry studies. Its hydrochloride form enhances solubility, making it suitable for various experimental and industrial applications.
