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