This chemical is primarily utilized in bioconjugation and crosslinking applications due to its dual azide functional groups, which enable efficient click chemistry reactions. It is commonly employed in the modification of biomolecules, such as proteins, peptides, and nucleic acids, to introduce polyethylene glycol (PEG) chains. This PEGylation enhances the stability, solubility, and bioavailability of the biomolecules, making it valuable in drug delivery systems and therapeutic development. Additionally, it is used in material science for surface functionalization and the creation of hydrogels or polymer networks with tailored properties. Its water-soluble nature and biocompatibility make it suitable for applications in biotechnology and biomedical research.
