I. [Product Description] 
    SVA-PEG-Threonine (Succinimidyl valerate-polyethylene glycol-threonine) is a high-purity organic intermediate widely used in the fields of bioconjugation and nanomaterial synthesis. Its core value lies in providing excellent hydrophilicity and steric hindrance effect through the PEG segment. Meanwhile, the threonine residue and the succinimide ester group endow the molecule with the ability of directional modification, which is suitable for the preparation of catalyst carriers and functionalized materials.
