Ald-Ph-PEG24-NHS ester linker contains a benzaldehyde moiety and an NHS group. The benzaldehyde group readily reacts with primary amines, aminooxy and hydrazide. The NHS ester undergoes amide coupling with amino-bearing molecules. The hydrophilic PEG chain increases the water solubility of the compound.
