Used in pharmaceutical research as a key intermediate in the synthesis of bioactive molecules, particularly in the development of central nervous system agents. Its spirocyclic structure and nitrogen functionality make it valuable for designing compounds with improved metabolic stability and receptor selectivity. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies, especially in programs targeting neurological disorders such as depression, anxiety, and addiction. Also utilized in the preparation of novel ligands for neurotransmitter receptors due to its conformational rigidity and favorable pharmacokinetic properties.
