This chemical is widely used in bioconjugation and click chemistry applications due to its dual azide functional groups, which enable efficient and specific reactions with alkyne-containing molecules. It serves as a versatile linker in the synthesis of complex biomolecules, such as peptides, proteins, and polymers, facilitating the creation of stable and well-defined structures. Its polyethylene glycol (PEG) spacer provides water solubility and biocompatibility, making it suitable for drug delivery systems, surface modifications, and the development of hydrogels. Additionally, it is employed in material science for functionalizing surfaces and nanoparticles, enhancing their stability and targeting capabilities in biomedical research.
