Aminooxy-PEG2-amine is a chemical reagent containing an aminooxy group and a primary amine. Aminooxy groups react with aldehydes to form oxime bonds. If a reducing agent is used, it will form a hydroxylamine bond. In the presence of the coupling agent EDC, the amino group reacts with an activated NHS ester or carboxylic acid. Aminooxy compounds are very reactive and sensitive; they cannot be stored for long periods of time.
