Used in bioconjugation and drug delivery systems, this compound serves as a linker molecule. Its PEG chain enhances solubility and biocompatibility, while the Boc group protects reactive sites during synthesis. The dibromo-maleimide moiety enables selective conjugation with thiol groups in peptides, proteins, or other biomolecules. It is particularly valuable in creating antibody-drug conjugates (ADCs) and targeted therapies, ensuring precise delivery of therapeutic agents. Additionally, it finds use in modifying surfaces for biosensors and diagnostic tools, improving stability and functionality.
