This chemical is widely used in the field of bioconjugation and drug delivery due to its unique properties. It serves as a linker molecule, connecting bioactive molecules, such as peptides or proteins, to other compounds or surfaces. Its polyethylene glycol (PEG) backbone provides excellent water solubility and reduces immunogenicity, making it ideal for enhancing the stability and circulation time of therapeutic agents in the body. Additionally, it is utilized in the development of hydrogels and biomaterials, where its bifunctional nature allows for cross-linking and the creation of stable, biocompatible networks. Its application extends to surface modification, where it is used to improve the biocompatibility of medical devices and nanoparticles.
