This chemical is widely used in bioconjugation and click chemistry applications due to its dual azide functional groups, which enable efficient and selective reactions with alkyne-containing compounds. It is particularly valuable in the development of biomaterials, drug delivery systems, and bioconjugate probes, where its polyethylene glycol (PEG) spacer enhances solubility and reduces steric hindrance. Additionally, it plays a significant role in the synthesis of crosslinked polymers and hydrogels, which are utilized in tissue engineering and controlled-release formulations. Its versatility also extends to labeling biomolecules, such as proteins and nucleic acids, for imaging and diagnostic purposes.
