This chemical is primarily utilized in bioconjugation and click chemistry applications. Its azide functional group enables efficient coupling with alkyne-containing molecules through copper-catalyzed azide-alkyne cycloaddition (CuAAC), making it valuable for labeling, modifying, or crosslinking biomolecules like proteins, peptides, or nucleic acids. The Boc (tert-butoxycarbonyl) protecting groups ensure selective reactivity, allowing controlled deprotection and stepwise synthesis. The PEG (polyethylene glycol) spacers enhance solubility, reduce steric hindrance, and improve biocompatibility, making it suitable for drug delivery systems, bioconjugate therapeutics, and materials science. Its versatility supports applications in targeted drug development, surface functionalization, and biomaterial engineering.
