Used primarily in research settings as a potent and selective antagonist of the cannabinoid receptor 1 (CB1). Its main application lies in studying the role of CB1 receptors in various physiological processes, including appetite regulation, energy balance, and reward mechanisms. Due to its high selectivity and blood-brain barrier penetration, it is valuable in neuroscience research to investigate the endocannabinoid system’s involvement in behaviors such as feeding, addiction, and mood. It has been explored in preclinical models for potential anti-obesity effects, though it remains strictly a research compound and is not approved for clinical or therapeutic use.
