Used primarily in bioconjugation and drug delivery systems, this compound serves as a linker molecule. Its structure allows for the attachment of therapeutic agents to targeting molecules, enhancing the precision of drug delivery. The sulfone group provides stability, while the PEG (polyethylene glycol) segments improve solubility and reduce immunogenicity. This chemical is particularly valuable in the development of antibody-drug conjugates (ADCs) and targeted cancer therapies, where it helps ensure that drugs reach specific cells with minimal off-target effects. Additionally, it is employed in the synthesis of biomaterials and in modifying surfaces for biomedical applications.
