Used in research to study serotonin pathways due to its role as an intermediate in serotonin synthesis. Helps in understanding neurochemical processes related to mood, sleep, and appetite regulation. Employed in biochemical assays requiring precise modulation of serotonin precursors. Also utilized in the development and testing of analytical methods for neurotransmitter metabolites. Stable under controlled conditions, making it suitable for long-term studies in neuropharmacology.
