This compound is widely used in the field of bioconjugation and drug delivery due to its polyethylene glycol (PEG) chains, which enhance solubility and stability. It is particularly valuable in modifying peptides, proteins, and other biomolecules to improve their pharmacokinetic properties, such as prolonged circulation time in the body. The hydroxyl groups on the PEG chains allow for further functionalization, making it a versatile linker in the synthesis of targeted therapeutics. Additionally, its Boc-protected amine group ensures selective reactivity, enabling precise conjugation strategies in complex chemical environments. This makes it a crucial component in the development of advanced drug delivery systems and bioconjugate vaccines.
