Used as an intermediate in the synthesis of biologically active compounds, particularly in pharmaceutical research targeting kinase inhibitors and other therapeutic agents. The aldehyde group allows for further functionalization via reactions such as reductive amination or Wittig-type transformations, enabling the introduction of diverse side chains. The Boc-protected piperidine provides a stable, protected amine handle suitable for peptide-like coupling or deprotection strategies in multistep syntheses. Commonly employed in medicinal chemistry for constructing modulators of metabolic and neurological targets.
