This chemical is widely used in bioconjugation and protein modification processes. Its structure includes a maleimide group, which reacts specifically with thiol groups in cysteine residues, making it ideal for attaching peptides, proteins, or antibodies to other molecules. The PEG8 spacer provides flexibility and solubility, reducing steric hindrance and improving the efficiency of the conjugation. The PFP ester group is highly reactive with amines, enabling the formation of stable amide bonds. This compound is particularly useful in drug delivery systems, where it can link therapeutic agents to targeting molecules, enhancing specificity and efficacy. It is also employed in the development of diagnostic probes and bioconjugate vaccines, where precise and stable molecular linkages are critical.
