Used primarily in research settings to study serotonin receptors due to its structural similarity to serotonin. It serves as a tool compound in pharmacological studies to understand receptor binding and signaling pathways. It is also employed in the development of new therapeutic agents targeting neurological disorders, such as depression and anxiety, by mimicking serotonin's effects. Additionally, it aids in exploring the role of serotonin in various physiological processes, including mood regulation and gastrointestinal function.
