Used as a crosslinking agent in polymer chemistry, particularly in the development of hydrogels and biocompatible materials. Enhances mechanical strength and stability of polymeric networks by forming disulfide bridges. Applied in drug delivery systems due to its reversible bond formation under redox conditions. Also utilized in bioconjugation techniques for protein modification and immobilization on surfaces. Shows potential in responsive materials that degrade under reducing environments, such as intracellular spaces.
