Used in biochemical research as a key intermediate in the synthesis of peptide-based pharmaceuticals and neuroactive compounds. It serves as a modified amino acid building block, particularly in the development of tryptophan-containing peptides that target serotonin receptors. Its structure supports studies on neurotransmitter regulation and neurodegenerative diseases. Also employed in the design of enzyme inhibitors and probes for studying metabolic pathways involving indole derivatives.
