N-(TCO)-N-bis(PEG4-acid) is a versatile click chemistry reagent featuring a terminal trans-cyclooctene (TCO) group and two terminal carboxylic acid moieties. This compound facilitates the formation of stable covalent bonds through inverse-electron demand Diels-Alder cycloaddition with tetrazine-containing molecules, representing one of the fastest and most selective bioorthogonal reactions. The carboxylic acids can also efficiently react with primary amino groups in the presence of common coupling activators, such as EDC or HATU, making this reagent suitable for various biochemical assays and labeling applications in research settings.
