I. [Product Description]
Mal-PEG-SH (Maleimide-Polyethylene Glycol-Thiol) is a bifunctional organic intermediate. The high-efficiency and specific binding property between its maleimide group and thiol group makes it a key cross-linking agent in bioconjugation reactions. This compound is widely used as a pharmaceutical intermediate in the field of molecular modification. Meanwhile, the polyethylene glycol (PEG) segment endows the product with excellent water solubility and stability, and it can be used as a catalyst carrier or reaction medium to optimize the system compatibility.
