Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors and other bioactive molecules. Its aldehyde group allows for easy functionalization via reductive amination or condensation reactions, enabling the introduction of diverse substituents. The tert-butyloxycarbonyl (Boc) protecting group stabilizes the amine during multi-step syntheses and can be readily removed under mild acidic conditions. Commonly employed in medicinal chemistry for constructing nitrogen-containing heterocycles and in the preparation of pyridine-based drug candidates.
