Product Information

Description	Carboxy-PEG9-phosphonic acid is a PEG linker with a carboxylic acid and a phosphonic acid group. The carboxylic acid can react with primary amines in the presence of activators such as EDC and HATU to form stable amide bonds. The hydrophilic PEG chain increases the water solubility of the compound in aqueous media.
