I. [Product Description] 
CHEMS-PEG-MAL (Cholesteryl hemisuccinate-Polyethylene glycol-Maleimide) is a multifunctional organic intermediate that combines the characteristics of the hydrophobic cholesterol group and the reactive maleimide group. It enables controllable modification and coupling through the PEG chain. As an efficient catalyst carrier and pharmaceutical intermediate, this compound is widely used in the construction of nanomaterials and the directional coupling of biomolecules. Its modular design supports precise regulation of molecular interactions.
