I. [Product Description]
COOH-PEG-Tryptophan is a highly efficient and multifunctional organic intermediate. Through the precise coupling of carboxyl groups with tryptophan and combined with the adjustable hydrophilicity of polyethylene glycol (PEG), it is widely used in bioconjugation reactions and the preparation of nanocarriers. Its unique molecular structure can serve as a catalyst carrier or pharmaceutical intermediate, significantly enhancing the stability and biocompatibility of the reaction system.
