This compound is primarily used in bioconjugation and chemical biology research. It serves as a linker or spacer molecule, enabling the attachment of functional groups or biomolecules to various substrates. The azido group allows for click chemistry reactions, particularly copper-catalyzed azide-alkyne cycloaddition (CuAAC), which is widely employed for labeling, imaging, and targeted drug delivery. The Boc (tert-butoxycarbonyl) group provides protection for amines during synthesis, ensuring selective reactivity. Additionally, the PEG2 (polyethylene glycol) spacer enhances solubility and reduces steric hindrance, improving the efficiency of conjugation processes. This makes it valuable in the development of biofunctional materials, drug delivery systems, and diagnostic probes.
