I. [Product Description]
SH-PEG-leucine (thiol-polyethylene glycol-leucine) is a multifunctional organic intermediate with both biocompatible polyethylene glycol (PEG) segments and active thiol and amino acid groups. It can be used as an efficient catalyst or pharmaceutical intermediate in bioconjugation reactions and polymer material synthesis. Its PEG segment provides excellent water solubility, and the leucine residue and thiol group endow precise molecular recognition and directional modification capabilities.
