I. [Product Description]
COOH-PEG-SS-PEG-COOH is a dicarboxyl-functionalized, disulfide-crosslinked polyethylene glycol organic intermediate with both precise molecular weight control and responsive cleavage properties. This compound can be used as a pharmaceutical intermediate to construct stimulus-responsive nanocarriers. Its PEG segments endow excellent water solubility and biocompatibility, and the disulfide bond structure can be specifically cleaved in a reducing environment, which is suitable for the design of scientific research systems requiring targeted release.
