I. [Product Description]
NHS-PEG-tyrosine (N-hydroxysuccinimide ester-polyethylene glycol-tyrosine) is a highly reactive organic intermediate. Its core value lies in the efficient carboxyl activation through the NHS ester group, which is suitable for crosslinking and modification in bioconjugation reactions. This compound combines the water solubility advantage of the PEG segment and the structural characteristics of tyrosine. It can be used as a pharmaceutical intermediate or a catalyst carrier to improve the reaction efficiency and product stability in the construction of complex molecules.
