This chemical is widely used in biochemical research, particularly in the study of protein interactions and modifications. It serves as a versatile reagent for introducing disulfide bonds or pyridyl disulfide groups into molecules, enabling the controlled conjugation of proteins or peptides. Its application is crucial in the development of drug delivery systems, where it facilitates the creation of targeted therapies by linking therapeutic agents to carriers. Additionally, it is employed in the synthesis of bioconjugates for diagnostic assays, enhancing the sensitivity and specificity of detection methods. Its ability to form reversible disulfide bonds makes it valuable in designing stimuli-responsive materials for biomedical applications.
