I. [Product Introduction]
Mal-PEG-CLS (Maleimide-Polyethylene Glycol-Cholesterol) is a multifunctional organic intermediate. It enables highly efficient and specific coupling through the maleimide group. The polyethylene glycol (PEG) chain enhances water solubility and biocompatibility, and the cholesterol structure endows it with excellent membrane anchoring ability. This compound is widely used in protein modification, nanocarrier construction, and biomaterial development. It is a key component in pharmaceutical intermediates and bioconjugation reaction catalysts.
