Used as a key intermediate in the synthesis of biologically active compounds, particularly in pharmaceutical research targeting central nervous system disorders. Its spirocyclic structure with fluorinated groups enhances metabolic stability and blood-brain barrier penetration, making it valuable in developing neuroactive agents. The ester groups allow for further functionalization, enabling the construction of complex molecules for structure-activity relationship studies. Commonly employed in medicinal chemistry for optimizing lead compounds with improved pharmacokinetic profiles.
