Used in research settings as a selective antagonist for the oxytocin receptor, particularly in studies related to social behavior, stress response, and reproductive physiology. It helps scientists investigate the role of oxytocin signaling in animal models without affecting vasopressin pathways, allowing for more precise experimental outcomes. Due to its high selectivity and blood-brain barrier permeability, it is valuable in neuroscience and behavioral pharmacology research. Not intended for clinical or therapeutic use in humans.
