I. [Product Description]
VA-PEG-SA (Valeric Acid-Polyethylene Glycol-Stearic Acid) is a multifunctional organic intermediate that constructs an amphiphilic molecular structure through precise block copolymerization technology. Its core value lies in the adjustable PEG segments, which endow it with excellent hydrophilic-hydrophobic balance properties and are widely used in polymer material modification and composite system construction. This compound combines the synthetic flexibility of pharmaceutical intermediates with the function of a catalyst carrier and is suitable for the design of complex reaction systems.
