Used as an intermediate in pharmaceutical synthesis, particularly in the development of active pharmaceutical ingredients (APIs) where protected piperidine moieties are required. Its carboxylic acid and Boc-protected amine groups allow for selective coupling reactions, making it valuable in constructing complex drug molecules. Commonly employed in medicinal chemistry for optimizing solubility, bioavailability, and binding affinity in target compounds. Suitable for solid-phase and solution-phase peptide-like synthesis due to its bifunctional reactivity.
