Used as a protected intermediate in the synthesis of indole-based pharmaceuticals. The tert-butoxycarbonyl (Boc) group stabilizes the nitrogen during reactions, while the hydroxyl group allows for further functionalization. Commonly applied in the development of serotonin receptor modulators, kinase inhibitors, and other bioactive molecules in medicinal chemistry. Also employed in the preparation of analogs for structure-activity relationship (SAR) studies due to its ease of deprotection and compatibility with various coupling reactions.
