I. [Product Description]
STA-PEG-COOH (Stearic Acid-Polyethylene Glycol-Carboxyl) is a multifunctional amphiphilic organic intermediate with both hydrophobic stearic acid segments and hydrophilic PEG segments. It can be efficiently chemically modified through the carboxyl group. As a key component in pharmaceutical intermediates and polymer material synthesis, it is widely used in the construction of nanocarriers, surface functionalization modification, and catalytic reaction systems, with excellent biocompatibility and reactivity.
