This chemical is primarily utilized in the field of bioconjugation and protein engineering. It serves as a crosslinking agent, enabling the formation of stable bonds between thiol-containing molecules, such as cysteine residues in proteins. This property makes it valuable in the development of antibody-drug conjugates (ADCs), where it helps link therapeutic agents to antibodies for targeted drug delivery. Additionally, it is employed in the modification of peptides and proteins to enhance their stability or functionality in biochemical research. Its disulfide bond can be selectively reduced, allowing for controlled release or activation of conjugated molecules in specific environments, such as within cells. This feature is particularly useful in designing responsive drug delivery systems and studying protein interactions.
