I. [Product Description]
Biotin-PEG-COOH is a high-purity biotin-polyethylene glycol-carboxylic acid derivative, which can be used as an organic intermediate or pharmaceutical intermediate in bioconjugation reactions and the preparation of functionalized materials. The biotin group in its molecular structure can efficiently bind to the avidin system, while the carboxylic acid group facilitates further modification or cross-linking, making it suitable for catalytic reactions and surface functionalization fields.
