Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of serotonin receptor modulators and other neuroactive compounds. Its structure supports the construction of complex indole-based molecules found in central nervous system drugs. Also employed in research settings for the preparation of fluorescent probes and biochemical tracers due to the reactivity of the amino and carboxylic acid groups. Commonly utilized in medicinal chemistry for scaffold modification in drug discovery programs targeting neurological disorders and migraines.
