This chemical is primarily utilized in bioconjugation and protein modification processes. It serves as a crosslinking agent, enabling the formation of stable bonds between biomolecules such as proteins, peptides, or antibodies. Its reactive groups, including N-hydroxysuccinimide (NHS) esters and disulfide bonds, facilitate efficient conjugation under mild conditions. This makes it particularly useful in the development of antibody-drug conjugates (ADCs) for targeted cancer therapies. Additionally, it is employed in the creation of bioconjugates for diagnostic assays, where precise and stable molecular linkages are essential. The disulfide bond within its structure allows for controlled release or cleavage in reducing environments, enhancing its versatility in drug delivery systems.
