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 the synthesis of peptide and protein conjugates, where it serves as a linker to improve pharmacokinetics and reduce immunogenicity. The Boc-protected groups allow for selective deprotection, enabling controlled modification of biomolecules. Additionally, it is utilized in the development of targeted therapeutics, such as antibody-drug conjugates (ADCs), where it facilitates the attachment of drugs to antibodies while maintaining their biological activity. Its application also extends to the creation of advanced materials and nanoparticles for biomedical research.
