Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of serotonin receptor modulators and central nervous system agents. Its structure supports the creation of bioactive molecules with potential applications in treating neurological and psychiatric disorders. Commonly employed in medicinal chemistry research for constructing indole-based compounds with therapeutic potential. Also utilized in the preparation of analogs for structure-activity relationship (SAR) studies due to its reactive amino and ester functional groups.
