This chemical is widely used in bioconjugation and peptide synthesis due to its bifunctional nature. It serves as a linker molecule, enabling the attachment of bioactive molecules or peptides to other substrates, such as polymers, surfaces, or proteins. The Boc (tert-butoxycarbonyl) group provides protection for amines during synthesis, ensuring selective reactions. The PEG2 (polyethylene glycol) spacer enhances solubility and reduces steric hindrance, improving the efficiency of conjugation. The amido and acid functional groups allow for further chemical modifications, making it versatile in drug delivery systems, targeted therapies, and the development of bioconjugates for research and pharmaceutical applications.
