4-IBP is primarily used in research settings to study the endocannabinoid system and its interactions with the body. It acts as a selective agonist for the CB1 receptor, making it valuable for investigating the physiological and psychological effects of cannabinoid receptor activation. Researchers utilize it to explore potential therapeutic applications, such as pain management, appetite regulation, and neurological disorders. Additionally, it helps in understanding the mechanisms of addiction and the role of cannabinoid receptors in the brain. Its specificity for CB1 receptors allows for precise studies without the interference of other receptor types.
