PEGs are useful hydrophilic linkers for bioconjugation. Diethyleneglycol, or PEG2, is a short PEG linker. This bifunctional molecule with an amino group that can be engaged in acylation reaction with anhydrides and activated esters, reductive amination with aldehydes and ketones, and alkylation with halides and epoxides, and other reactions. Its terminal alkyne group reacts with azides in copper-catalyzed CuAAC reaction and palladium-catalyzed Sonogashira coupling with aryl- and vinyl halides and triflates.

Alkyne-PEG3-OH is a triethyleneglycol based bifunctional linker with a hydroxyl group and an alkyne fragment.

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.
