TRAM 39 is primarily used as a research compound in pharmacological studies, particularly in the investigation of serotonin receptors. It serves as a selective agonist for the 5-HT2C receptor subtype, making it a valuable tool for understanding the role of this receptor in behaviors related to appetite, mood, and addiction. Due to its selectivity, TRAM 39 helps scientists differentiate the effects of 5-HT2C activation from other serotonin receptor activities, supporting the development of targeted therapies for obesity, depression, and substance use disorders. It is not used clinically but remains important in preclinical research for validating drug targets and assessing neurochemical pathways.
