Used in bioconjugation and drug delivery systems, it serves as a linker molecule to attach bioactive molecules to polymers or nanoparticles. The Boc group provides protection for amines during synthesis, while the PEG spacer enhances solubility and reduces immunogenicity. The terminal bromoalkyl group allows for further functionalization, making it valuable in creating targeted therapeutic agents or diagnostic probes. It is also employed in material science for surface modification and in peptide synthesis to introduce specific functionalities.
