Used in pharmaceutical research as a key intermediate in the synthesis of serotonin receptor modulators and other neuroactive compounds. Its structure supports the development of agents targeting central nervous system disorders, including anxiety, depression, and migraines. Commonly employed in medicinal chemistry for building indole-based scaffolds due to its reactive ester and halogen functionalities, enabling further derivatization. Also utilized in the preparation of tryptamine analogs and investigational drugs involving substituted indoles.
