Bis-aminooxy-PEG7 molecule contains two aminooxy groups. The hydrophilic PEG spacer increases solubility in aqueous media. Aminooxy (ONH2) group is reactive with an aldehyde to form an oxime bond or a hydroxylamine linkage under reduction condition Aminooxy compounds are very reactive and sensitive; they cannot be stored for long term. Immediate use (within 1 week) is highly recommended.
