Used as an intermediate in pharmaceutical synthesis, particularly in the development of kinase inhibitors and other bioactive molecules. The aldehyde group enables further functionalization through reactions such as reductive amination or Wittig transformations, allowing for the introduction of complex side chains. The tert-butyl carbamate (Boc) group serves as a protected amine, offering stability during synthetic steps and can be selectively removed under acidic conditions to release the free amine when needed. Commonly employed in medicinal chemistry for constructing nitrogen-containing heterocycles and in the preparation of pyridine-based drug candidates.
