This compound is widely used in bioconjugation and chemical biology research. It serves as a linker or spacer molecule, enabling the attachment of biomolecules such as peptides, proteins, or antibodies to other functional groups or surfaces. The Cbz (carbobenzyloxy) group provides protection for the aminooxy functionality, which can be selectively deprotected for further reactions. The PEG8 (polyethylene glycol) spacer enhances solubility and reduces steric hindrance, making it ideal for creating stable and biologically active conjugates. It is particularly useful in drug delivery systems, where it helps in the targeted release of therapeutic agents, and in diagnostic applications for labeling and detection purposes.
