Used as a key intermediate in the synthesis of indole-based pharmaceuticals, particularly in the development of serotonin receptor modulators and anti-migraine agents. Its 3-formyl aldehyde, 7-benzyloxy protected hydroxyl, and N-1 tert-butoxycarbonyl (Boc) protecting group allow selective functionalization, enabling the construction of complex molecular architectures in medicinal chemistry. The Boc group protects the indole nitrogen during multi-step syntheses and can be deprotected under mild acidic conditions. Commonly employed in organic syntheses where controlled reactivity and stability are required.
