This chemical is widely used in bioconjugation and drug delivery systems due to its ability to form stable disulfide bonds with thiol-containing molecules. It is particularly valuable in the development of targeted therapeutic agents, such as antibody-drug conjugates (ADCs), where it serves as a linker to attach cytotoxic drugs to antibodies. The disulfide bond allows for controlled release of the drug in the reducing environment of target cells, enhancing specificity and minimizing off-target effects. Additionally, it is employed in liposome formulations to improve the stability and functionality of lipid-based delivery systems, enabling efficient transport of therapeutic agents to specific tissues or cells. Its application extends to research in biochemistry and molecular biology for labeling and cross-linking proteins or peptides, facilitating studies on protein interactions and cellular processes.
