I. [Product Description]
NHS-PEG-CHEMSN-N-hydroxysuccinimide ester-polyethylene glycol-cholesterol hemisuccinate is a multifunctional organic intermediate. It enables efficient coupling reactions through the NHS active ester and is widely used in the fields of biomacromolecule modification and nano-carrier preparation. The cholesterol group in its structure can enhance hydrophobic interactions, and the PEG chain provides excellent water solubility and biocompatibility. It is suitable for catalyst carriers, the construction of drug delivery systems, and the development of functional materials.
