Used in bioconjugation, this compound is valuable for attaching biomolecules to surfaces or other molecules via click chemistry. Its biotin moiety allows for strong binding to streptavidin or avidin, enabling detection or purification processes. The PEG2 spacer enhances solubility and reduces steric hindrance, while the azide group facilitates efficient and specific reactions with alkyne-functionalized molecules. Commonly applied in drug delivery, diagnostics, and biochemical research to create targeted and stable conjugates.
