mPEG4-Acid (mPEG4-Carboxylic Acid, mPEG4-COOH) is a PEG derivative with a carboxylic acid at one end. The carboxylic acid can react with primary amine groups in the activators, such as EDC, or HATU, to form a stable amide bond. Due to its hydrophilicity, the PEG spacer can increase solubility in aqueous media.
