Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors and other bioactive molecules. The aldehyde group allows for further functionalization through reactions such as reductive amination or Wittig reactions, enabling the construction of complex molecular architectures. The tert-butyloxycarbonyl (Boc) protecting group stabilizes the amine during synthetic transformations and can be easily removed under mild acidic conditions when needed. Its structure is especially valuable in medicinal chemistry for assembling heterocyclic systems found in drug candidates.
