Used in pharmaceutical research as a key intermediate in the synthesis of bioactive indole derivatives. It serves as a building block for developing serotonin receptor modulators and other neuroactive compounds. Commonly employed in the preparation of analogs for drug discovery programs targeting central nervous system disorders. Also utilized in the development of anti-inflammatory and anticancer agents due to the indole scaffold’s prevalence in medicinal chemistry. Its ester functionality allows for easy modification, making it valuable in structure-activity relationship studies.
