I. [Product Description]
SS-PEG-SPDP is a multifunctional organic intermediate based on the dynamic response characteristics of disulfide bonds. It imparts excellent water solubility and biocompatibility through the polyethylene glycol (PEG) segment and combines the high-efficiency coupling activity of N-hydroxysuccinimide 3-(2-pyridyldithio)propionate (SPDP). It is widely used in bioconjugation reactions, surface modification of nanomaterials, and the construction of catalytic systems. This compound can be used as a pharmaceutical intermediate or a cross-linking agent to achieve precise and controllable molecular connection and release.
