This chemical is widely used in peptide synthesis, particularly as a building block for solid-phase peptide synthesis (SPPS). Its Fmoc-protected amine group allows for selective deprotection during the synthesis process, enabling the stepwise construction of peptides. The carboxymethyl group on the piperidine ring provides a functional handle for further modifications or conjugation, making it valuable in the development of peptide-based drugs and biomaterials. Additionally, it is employed in the preparation of peptidomimetics and other bioactive compounds, where the piperidine moiety can influence the pharmacokinetic and pharmacodynamic properties of the final product. Its application extends to research in medicinal chemistry, where it aids in the design of molecules with enhanced stability, bioavailability, and target specificity.
