- Description
Hydroxy-PEG2-acid sodium salt is a PEG linker bearing a terminal hydroxyl group and a terminal carboxylic acid presented as the sodium salt. The sodium salt form offers improved stability for storage and shipping compared with the free acid form. The terminal carboxylic acid can react with primary amines in the presence of activators such as EDC or HATU to form amide bonds, while the hydroxyl group supports further derivatization. The hydrophilic PEG spacer contributes to solubility in aqueous media.
