I. [Product Description]
VA-PEG-SH (Valeric acid-Polyethylene glycol-Thiol) is a multifunctional organic intermediate that combines a hydrophobic valeric acid group, a hydrophilic PEG chain, and a highly reactive thiol group. It is suitable for biological conjugation, nanomaterial synthesis, and catalytic system construction. Its modular structure allows for precise regulation of molecular polarity, solubility, and interfacial reactivity, and it has significant application value in the preparation of pharmaceutical intermediates and the design of polymer catalysts.
