TCO-PEG4-TCO is a bifunctional click chemistry reagent with TCO moieties at both ends of the molecule. TCO group enable click chemistry with tetrazine. The hydrophilic PEG linker increases the solubility of compounds in aqueous media.

TCO-PEG4-TCO is a PEG-based PROTAC linker can be used in the synthesis of PROTACs[1].
