I. [Product Description]
Biotin-PEG-PEI (Biotin-Polyethylene Glycol-Polyethyleneimine) is a multifunctional organic intermediate. Through precise molecular design, it integrates the high affinity of biotin, the biocompatibility of PEG, and the efficient cationic properties of PEI. This compound has important application values in the construction of nanocarriers, the coupling of biomolecules, and the development of catalytic systems. It can be used as a pharmaceutical intermediate or a catalyst carrier.
