I. [Product Description]
VS-PEG-Leucine is a multifunctional organic intermediate that enables efficient bioconjugation through the vinyl sulfone group. It is suitable for the synthesis of pharmaceutical intermediates and catalytic reaction systems. Its polyethylene glycol (PEG) segment imparts excellent water solubility and biocompatibility, and the leucine structure can directionally regulate molecular recognition properties, making it of great value in the field of biomaterial modification.
