This chemical is widely used in the development of drug delivery systems due to its ability to enhance solubility and bioavailability of therapeutic compounds. Its polyethylene glycol (PEG) chains make it highly effective in creating biocompatible and stable conjugates, which are essential for targeted drug delivery. It is also utilized in the synthesis of hydrogels and other biomaterials, providing controlled release properties for pharmaceuticals. Additionally, it plays a role in surface modification of nanoparticles, improving their stability and circulation time in biological systems. Its applications extend to bioconjugation techniques, where it is used to link biomolecules for diagnostic and therapeutic purposes.
