This chemical is widely utilized in the field of bioconjugation and drug delivery due to its dual functional groups, which enable the creation of stable linkages between molecules. Its polyethylene glycol (PEG) chains enhance solubility and reduce immunogenicity, making it ideal for modifying proteins, peptides, and other biomolecules. It is often employed in the development of antibody-drug conjugates (ADCs) to improve therapeutic efficacy and reduce off-target effects. Additionally, it is used in the synthesis of hydrogels and other biocompatible materials for tissue engineering and controlled drug release applications. Its versatility also extends to nanotechnology, where it serves as a spacer or linker in the design of nanoparticles for targeted drug delivery systems.
