Used in research to study neurotensin receptors due to its potent and selective antagonistic properties. It helps in understanding the role of neurotensin in neurological and psychiatric disorders, such as schizophrenia and Parkinson's disease. Also applied in pharmacological studies to explore potential therapeutic interventions targeting neurotensin pathways. Its use in preclinical models aids in evaluating the effects of receptor modulation on behavior, cognition, and cellular signaling.
