Biotin-PEG4-azide is used for bioconjugation purposes, particularly in conjunction with click chemistry reactions. The azide group can react with alkynes in a copper-catalyzed azide-alkyne cycloaddition (CuAAC) or strain-promoted azide-alkyne cycloaddition (SPAAC) reaction. This enables specific and efficient labeling of biomolecules (such as proteins, peptides, or nucleic acids) or surfaces. Azide reacts specifically with alkynes (-C≡CH) in a copper-catalyzed or copper-free manner to form 1,2,3-triazoles, which are stable linkages in biological systems.
