Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors and other bioactive molecules. The aldehyde group (formyl) allows for further functionalization via reactions such as reductive amination or condensation, enabling the introduction of diverse side chains. The tert-butoxycarbonyl (Boc) protecting groups stabilize the amine functionality during multi-step syntheses and can be selectively removed under mild acidic conditions. Its structure is especially valuable in medicinal chemistry for constructing complex heterocyclic systems found in drug candidates. Commonly employed in solid-phase and solution-phase peptide-like synthesis where controlled reactivity and solubility are required.
