I. [Product Description]
SH-PEG-Valine (Thiol-Polyethylene Glycol-Valine) is a multifunctional organic intermediate. Through the synergistic effect of thiol and polyethylene glycol, it significantly enhances the water solubility and biocompatibility of compounds. As a pharmaceutical intermediate, it is widely used in bioconjugation, polymer material modification, and catalytic reaction systems, with both high-precision coupling efficiency and controllable molecular weight characteristics.
