Used as a crosslinking agent in the synthesis of biomaterials, particularly in drug delivery systems, where it enhances the stability and solubility of therapeutic compounds. It is also employed in bioconjugation techniques to attach polyethylene glycol (PEG) chains to proteins or peptides, improving their pharmacokinetic properties and reducing immunogenicity. Additionally, it serves as a spacer in the development of hydrogels and other polymeric materials, providing flexibility and controlled release of active agents.
