This chemical is widely used in the field of bioconjugation and drug delivery systems. Its primary application lies in its ability to act as a linker or spacer molecule, connecting bioactive molecules to nanoparticles, proteins, or other therapeutic agents. The polyethylene glycol (PEG) chain enhances solubility, reduces immunogenicity, and improves the stability of the conjugated compounds, making it particularly valuable in the development of targeted drug delivery systems. Additionally, it is utilized in the synthesis of hydrogels and other biomaterials, where its properties contribute to controlled release mechanisms and improved biocompatibility. Its versatility also extends to research applications, such as modifying surfaces for biosensors or creating functionalized polymers for advanced material science.
