This compound is widely used in bioconjugation and drug delivery systems due to its ability to link biomolecules selectively. Its maleimide group reacts efficiently with thiol groups, making it ideal for attaching peptides, proteins, or antibodies to polymers or nanoparticles. In targeted cancer therapies, it helps in creating drug conjugates that deliver chemotherapeutic agents directly to tumor cells, minimizing side effects. Additionally, it is employed in the development of hydrogels for tissue engineering, where it facilitates cross-linking to create stable, biocompatible structures. Its PEG (polyethylene glycol) segment enhances solubility and reduces immunogenicity, making it suitable for various biomedical applications.
