This compound is widely used in bioconjugation and drug delivery systems due to its polyethylene glycol (PEG) spacer, which enhances solubility and reduces immunogenicity. The Boc (tert-butoxycarbonyl) protecting group allows for selective deprotection in peptide synthesis, making it valuable in the development of therapeutic peptides and proteins. Additionally, its amine-reactive terminal enables coupling with various biomolecules, such as antibodies, proteins, or small molecules, for targeted delivery or diagnostic applications. It is also employed in the creation of PEGylated linkers for controlled release formulations in pharmaceuticals.
