This chemical is widely utilized in bioconjugation and click chemistry applications due to its azido and PEGylated structure. Its azide group enables efficient and selective reactions with alkynes via copper-catalyzed azide-alkyne cycloaddition (CuAAC), making it valuable for labeling, modifying, or crosslinking biomolecules such as proteins, peptides, and nucleic acids. The PEG (polyethylene glycol) chains enhance solubility and biocompatibility, reducing immunogenicity and improving stability in biological systems. Additionally, the Boc (tert-butyloxycarbonyl) protecting groups allow for controlled deprotection, enabling stepwise functionalization in synthetic processes. This compound is particularly useful in drug delivery systems, surface modification, and the development of bioconjugates for therapeutic and diagnostic purposes.
