Used primarily as a functional monomer in polymer chemistry, this compound enables the introduction of pyridyl disulfide groups into polymers, facilitating reversible conjugation with thiol-containing molecules. It is widely applied in bioconjugation, drug delivery systems, and surface modification of biomaterials due to its ability to form disulfide bonds that are stable under physiological conditions but cleavable in reducing environments. Commonly employed in the synthesis of smart hydrogels, self-assembling polymers, and targeted therapeutics where controlled release is required. Its methacrylate group allows copolymerization with other acrylic monomers via free radical polymerization, while the disulfide linker supports dynamic or responsive behavior in the final material. The MEHQ stabilizer prevents premature polymerization during storage.
