Used primarily in the field of bioconjugation, this chemical serves as a crosslinking agent to attach biomolecules, such as proteins or peptides, to other molecules or surfaces. Its maleimide group reacts selectively with thiol groups, while the isocyanate group can react with amines or hydroxyl groups, making it highly versatile for creating stable covalent bonds. It is often employed in the development of antibody-drug conjugates, biosensors, and targeted drug delivery systems. Additionally, it is utilized in material science for modifying polymers or surfaces to enhance their functionality in biomedical applications.
