I. [Product Description]
COOH-PEG-Biotin (Carboxyl-Polyethylene Glycol-Biotin) is a multifunctional organic intermediate, combining the high-affinity targeting property of biotin and the biocompatibility of the PEG chain. It is widely used in the fields of bioconjugation and nanomaterial modification. This compound can serve as an efficient catalyst carrier or a pharmaceutical intermediate, and its PEG chain can significantly improve water solubility and molecular stability.
