NH2-PEG-acid, TFA salt, MW 5,000 constitutes a bifunctional PEG polymer consisting of a primary amine that is free to perform a wide variety of reactions such as coupling with carboxylic acids, reductive aminations with ketones or aldehydes, or other more specialized uses. The carboxylic acid can react with primary amine groups in the presence of activators such as HATU. The 5k polyPEG linking the two groups improves the solubility of the molecule in aqueous media.
