Used primarily in neuroscience research to study serotonin receptors, particularly the 5-HT1A subtype. It acts as a selective agonist, helping to understand the role of serotonin in mood regulation, anxiety, and depression. Applied in behavioral studies to investigate its effects on anxiety-like and depression-like behaviors in animal models. Also utilized in pharmacological experiments to explore its potential therapeutic applications for psychiatric disorders. Additionally, it aids in mapping serotonin receptor distribution in the brain through radiolabeling techniques.
