Used primarily in research settings as a selective sigma-1 receptor ligand, this compound plays a role in studying neurological pathways associated with pain, neurodegenerative diseases, and psychiatric disorders. Its spirocyclic structure enhances binding specificity, making it valuable in pharmacological assays to evaluate receptor function and drug efficacy. It is also employed in radiolabeled form to map sigma receptor distribution in brain tissue. Due to its high affinity and selectivity, it serves as a reference tool compound in neuroscience and medicinal chemistry research.
