Used primarily in pharmaceutical research as a potent and selective serotonin 5-HT1A receptor ligand. It serves as an intermediate in the synthesis of compounds with potential anxiolytic and antidepressant activity. Due to its high affinity for 5-HT1A receptors, it is employed in neuropharmacological studies to investigate serotonin signaling pathways and receptor behavior. Also utilized in radiolabeled form for receptor binding assays and imaging studies in preclinical models. Its stability and specificity make it valuable in developing novel central nervous system therapeutics.
