This compound is primarily used in bioconjugation and chemical biology research. It serves as a linker or crosslinker in the development of drug delivery systems, particularly for creating stimuli-responsive nanocarriers. The disulfide bond (SS) in its structure allows for targeted release of therapeutic agents in reducing environments, such as inside cancer cells. The azide groups enable click chemistry reactions, facilitating efficient attachment to biomolecules or nanoparticles. Its PEG (polyethylene glycol) components enhance solubility and biocompatibility, making it suitable for in vivo applications. It is also utilized in the synthesis of hydrogels and polymer networks for tissue engineering and regenerative medicine.
