Used as an intermediate in pharmaceutical synthesis, 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 chemistry, enabling the introduction of diverse side chains. The tert-butyloxycarbonyl (Boc) protecting group stabilizes the amine during synthetic transformations and can be readily removed under acidic conditions when needed. Its structure is well-suited for use in medicinal chemistry campaigns targeting pyridine-based scaffolds, which are common in drug discovery due to their favorable pharmacokinetic properties and ability to engage in hydrogen bonding.
