This compound is widely used in bioconjugation processes, particularly for linking biomolecules such as peptides, proteins, or antibodies to other entities. Its PFP ester group reacts efficiently with primary amines, enabling stable amide bond formation, while the PEG spacer enhances solubility and reduces steric hindrance. It is commonly applied in drug delivery systems to create targeted therapies, in diagnostic assays for labeling biomolecules, and in research for studying protein interactions. Its versatility makes it a valuable tool in developing bioconjugates with improved stability and functionality.
