Used in bioconjugation, it facilitates the linking of biomolecules by reacting with carbonyl groups, enabling the attachment of proteins, peptides, or other molecules for research or therapeutic purposes. It is also applied in drug delivery systems to enhance the stability and targeting efficiency of therapeutic agents. Additionally, it serves as a crosslinker in material science for modifying surfaces or creating functionalized polymers. Its PEG spacer improves solubility and reduces immunogenicity in biomedical applications.
