Used primarily as a key intermediate in the synthesis of pharmaceutical compounds, especially in the development of indole-based drugs. Its functional groups allow for selective modifications, making it valuable in constructing complex molecules for medicinal chemistry. Commonly employed in the preparation of serotonin receptor agonists and antagonists due to the indole scaffold’s biological relevance. Also utilized in the production of agrochemicals and functional materials where substituted indoles are required. The bromomethyl group enables easy coupling with nucleophiles, facilitating the introduction of various side chains in drug design.
