I. [Product Description]
COOH-PEG-STA is a multifunctional organic intermediate. Through the bifunctional modification of carboxyl group and monostearic acid, it has both hydrophilic and hydrophobic amphiphilic properties. It can be used as a key linking module for pharmaceutical intermediates or polymer material synthesis. Its adjustable PEG chain length provides a basis for precise molecular design in the construction of nanocarriers and interface modification.

II. [Product Details]
