This chemical is widely used in the field of bioconjugation and drug delivery systems. It serves as a versatile linker for attaching various molecules, such as peptides, proteins, or drugs, to other functional groups or surfaces. The Boc (tert-butoxycarbonyl) group provides protection for the amine during synthesis, while the PEG (polyethylene glycol) spacer enhances solubility and reduces immunogenicity. The carboxylic acid group at the end allows for further conjugation through amide bond formation, making it valuable in creating targeted therapeutics or diagnostic agents. Additionally, it is employed in the development of bioconjugates for cancer therapy, where precise targeting and controlled release of drugs are crucial. Its stability and flexibility also make it suitable for use in material science, particularly in modifying surfaces for biomedical applications.
