Widely used in bioconjugation and drug delivery systems, this compound serves as a linker to attach therapeutic agents or targeting molecules to nanoparticles or proteins. Its polyethylene glycol (PEG) chains enhance solubility and stability, reducing immunogenicity and extending circulation time in biological systems. It is also employed in the development of hydrogels for tissue engineering, providing a biocompatible and flexible matrix for cell growth and differentiation. Additionally, it plays a role in surface modification of materials to improve biocompatibility and reduce non-specific interactions in biomedical applications.
