Used in research settings as a selective antagonist for the oxytocin receptor, helping to study the role of oxytocin in social behavior, reproduction, and stress responses. It is valuable in neuroscience and pharmacology for understanding neuroendocrine functions and has been explored in preclinical models to investigate conditions like anxiety, autism, and childbirth-related disorders. Due to its specificity, it allows scientists to block oxytocin signaling without affecting related hormones, making it a critical tool in receptor-level studies.
