I. [Product Description]
COOH-PEG-leucine is a multifunctional organic intermediate. In its structure, the carboxyl end is connected to the leucine residue through a polyethylene glycol (PEG) chain, combining biocompatibility and chemical modifiability. This compound can be used as a pharmaceutical intermediate in the construction of targeted delivery systems or as a catalyst carrier to play a key role in asymmetric synthesis. The adjustable molecular weight of its PEG chain significantly enhances the application flexibility.
