Ald-Ph-PEG2-NH-Boc linker contains a benzaldehyde group and a Boc protected amine group. Aldehyde readily react with hydrazide and aminooxy groups. After de-Boc, the free primary amine can react with carboxylic acids, activated NHS esters and other carbonyl compounds. The hydrophilic PEG linker can increase the water solubility of the compound.
