Used primarily as a crosslinking agent in biochemical and bioconjugation processes, it enables the formation of disulfide bonds between molecules, which is crucial for stabilizing protein structures or creating drug delivery systems. It is also employed in modifying peptides and proteins to enhance their functionality or targeting capabilities in therapeutic applications. Additionally, it serves as a linker in the synthesis of antibody-drug conjugates, facilitating the attachment of cytotoxic agents to antibodies for targeted cancer therapy. Its ability to form reversible bonds makes it valuable in controlled-release systems and biosensor development.
