Widely used in neuroscience research to study the role of serotonin in the brain and its impact on mood, behavior, and cognitive functions. It serves as a key compound in experiments involving serotonin receptors and neurotransmitter pathways. Additionally, it is utilized in pharmacological studies to develop and test drugs targeting depression, anxiety, and other mental health disorders. In cell culture studies, it helps investigate serotonin's effects on cellular processes and signal transduction. It is also employed in biochemical assays to measure serotonin levels and understand its metabolism in various biological systems.
