Tetrazine-PEG5-NHS Ester is one of the most reactive tetrazines commercially available. Hydrogen substituted tetrazines demonstrate exceptionally fast kinetics, generally at least 10 fold faster compared to methyl substituted tetrazines. The aqueous solubility of this reagent is substantially enhanced by a hydrophilic polyethylene glycol (PEG) spacer arm.
