This chemical is widely used in bioconjugation and click chemistry applications due to its unique structure that includes two propargyl groups. These groups enable efficient and selective reactions with azide-containing compounds, making it valuable for labeling, modifying, and crosslinking biomolecules such as proteins, peptides, and nucleic acids. It is particularly useful in the development of drug delivery systems, where it helps create stable and functional linkages. Additionally, its PEG (polyethylene glycol) spacer enhances solubility and reduces immunogenicity, making it suitable for biomedical research and therapeutic applications. It is also employed in material science for surface functionalization and the creation of advanced polymeric materials.
