This chemical is widely used in bioconjugation and drug delivery systems due to its polyethylene glycol (PEG) chains, which enhance solubility and stability. It is particularly valuable in modifying biomolecules, such as proteins and peptides, to improve their pharmacokinetics and reduce immunogenicity. The Boc-protected groups allow for controlled deprotection, enabling precise conjugation strategies. Its application extends to the development of targeted therapies, where it facilitates the attachment of bioactive molecules to carriers or surfaces. Additionally, it is utilized in the synthesis of complex drug conjugates, contributing to advancements in cancer treatment and other therapeutic areas.
