Used as an intermediate in pharmaceutical synthesis, particularly in the production of indole-based bioactive compounds. It serves as a protected indole derivative, allowing selective functionalization at other positions of the indole ring during multi-step reactions. Commonly employed in the development of serotonin receptor modulators, kinase inhibitors, and anti-inflammatory agents. Its tert-butoxycarbonyl (Boc) group stabilizes the nitrogen, enabling cleaner reactions and easier purification in drug discovery processes. Also utilized in agrochemical research for designing novel active ingredients.
