I. [Product Description]
SH-PEG-NTA-Ni is a multifunctional organic intermediate, which combines the directional coupling ability of sulfhydryl group (-SH), the biocompatibility of polyethylene glycol (PEG), and the metal chelating property of NTA-Ni. This compound is widely used in catalyst design, protein immobilization, and surface modification of nanomaterials. Its modular structure can be flexibly adapted to the needs of pharmaceutical intermediate synthesis and functional material development.
