I. [Product Description]
COOH-PEG-valine is a high-purity organic intermediate with the dual-functional modification characteristics of carboxyl group and valine. It can serve as a key linking unit or surface modifier in bioconjugation reactions. The PEG segment in its molecule endows excellent water solubility and biocompatibility, making it suitable for catalyzing the synthesis and functional modification of polymer materials. The molecular weight can be custom-designed to meet different experimental needs.

II. [Product Details]
