I. [Product Description]
Biotin-PEG-CLS is a multifunctional organic intermediate. Through the precise coupling of biotin, polyethylene glycol (PEG) with adjustable molecular weight, and cholesterol groups, it is widely used in the fields of bioconjugation and nanocarrier construction. Its core value lies in using the PEG chain to enhance water solubility and stability, combining the high-specificity binding ability of biotin and the membrane-anchoring property of cholesterol to provide an efficient molecular connection platform for pharmaceutical intermediates and catalytic reaction systems.
