Used in bioconjugation and protein modification, this compound is highly effective for linking biomolecules due to its maleimide group, which reacts selectively with thiols. The PEG6 spacer enhances solubility and reduces steric hindrance, improving the efficiency of the conjugation process. The pentafluorophenyl ester group reacts with amines, enabling stable amide bond formation. It is particularly useful in drug delivery systems, antibody-drug conjugates, and the development of targeted therapies. Its versatility makes it a valuable tool in biomedical research and therapeutic applications.
