This chemical is widely used as a crosslinking agent in the synthesis of hydrogels, which are essential in drug delivery systems and tissue engineering. Its bifunctional structure allows it to form stable covalent bonds with polymers, enhancing the mechanical strength and biocompatibility of the resulting materials. Additionally, it is employed in surface modification to improve the adhesion and functionality of biomaterials. In bioconjugation, it serves as a linker to attach bioactive molecules, such as peptides or proteins, to nanoparticles or other carriers, facilitating targeted therapeutic applications. Its water-soluble PEG segment further enhances its utility in biomedical and pharmaceutical formulations.
