Oligoethylene glycols are versatile hydrophilic linkers. Each monomer has a length of 3.43 Å, so the length of PEG4 is around 14 Å (1.4 nm).

Azide-PEG4-amine is a bifunctional compound with an amine group that can be modified by acylation by activated esters or similar carbonyl compounds and an azide group that is suitable for click chemistry reactions. PEG4 is highly hydrophilic and biocompatible.

Thalidomide-O-PEG2-azide

Thalidomide-containing building block with PEG2-linker and azide function group for conjugation with alkyne-functionalized linkers and target protein ligands through click chemistry reactions.

THPTA ligand

THPTA is a water-soluble ligand for Cu(I)-catalyzed click chemistry. The ligand stabilizes copper in its Cu(I) oxidation state. Due to high aqueous solubility, reactions with this ligand do not require an organic co-solvent.
