I. [Product Description]
SH-PEG-VA (Thiol-Polyethylene Glycol-Valeric Acid) is a multifunctional organic intermediate with both biocompatible coupling and controllable modification properties. The thiol and valeric acid groups in its molecule can serve as efficient cross-linking agents or catalysts, which are widely used in the synthesis of polymer materials and the preparation of pharmaceutical intermediates. The PEG segment endows it with excellent water solubility and adjustable steric hindrance.
