This chemical is widely used in the field of bioconjugation and drug delivery systems. It serves as a linker molecule with a maleimide group that enables selective attachment to thiol-containing biomolecules such as proteins, peptides, or nanoparticles, and a T-Boc protected amino group for subsequent deprotection and functionalization of bioactive molecules. Its PEG (polyethylene glycol) spacer enhances solubility and reduces immunogenicity, making it ideal for creating targeted therapeutic agents. The T-Boc protecting group allows for selective deprotection, facilitating controlled reactions in complex synthetic processes. It is particularly valuable in the development of antibody-drug conjugates (ADCs) and other biopharmaceuticals where precise and stable conjugation is critical.
