This chemical is primarily utilized in the field of bioconjugation and drug delivery systems. Its structure, featuring multiple PEG (polyethylene glycol) chains, makes it highly effective in improving the solubility and stability of therapeutic compounds. It is often employed to modify proteins, peptides, and other biomolecules, enhancing their pharmacokinetic properties by reducing immunogenicity and prolonging circulation time in the body. Additionally, it is used in the development of targeted drug delivery systems, where it helps in attaching drugs to specific ligands or antibodies, ensuring precise delivery to diseased tissues. Its application is also significant in the preparation of hydrogels and other biomaterials, where it contributes to creating biocompatible and biodegradable matrices for tissue engineering and regenerative medicine.
