This chemical is widely used in bioconjugation and drug delivery systems due to its PEGylated structure, which enhances solubility, stability, and biocompatibility. It is particularly valuable in the development of prodrugs and targeted therapies, where the PEG chains help improve pharmacokinetics and reduce immunogenicity. The Boc (tert-butoxycarbonyl) group serves as a protective group for amines, allowing selective deprotection during synthesis. Additionally, the presence of multiple PEG-alcohol groups enables further functionalization, making it suitable for creating linkers in antibody-drug conjugates (ADCs) or other bioconjugates. Its application extends to nanotechnology, where it is used to modify surfaces of nanoparticles for improved drug delivery efficiency and reduced toxicity.
