Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of serotonin receptor modulators and other central nervous system agents. Its structure supports the construction of complex indole-based molecules with potential activity in treating neurological and psychiatric disorders. Commonly employed in medicinal chemistry research for generating analogs in drug discovery programs targeting migraine, anxiety, and depression. Also utilized in the preparation of fluorescent probes and biochemical tools for studying enzyme activity and receptor binding.
