This chemical is widely used in bioconjugation and drug delivery systems due to its dual Boc-protected amine groups and PEG (polyethylene glycol) spacers. The Boc groups provide protection for the amines during synthesis, allowing selective deprotection when needed. The PEG spacers enhance solubility, reduce immunogenicity, and improve the pharmacokinetics of conjugated molecules. It is particularly useful in the development of peptide-based therapeutics, where it serves as a linker to attach drugs, targeting ligands, or imaging agents. Additionally, its application extends to the creation of hydrogels and biomaterials for controlled release systems, where the PEG chains contribute to biocompatibility and stability.
