Methyltetrazine-amido-PEG8-amine Trifluoroacetate

Methyltetrazine-amido-PEG8-amine Trifluoroacetate is a heterobifunctional linker with a terminal methyltetrazine group, allowing it to react with TCO-containing compounds without the need for Cu-catalysis or high temperatures. It also features a terminal amine capable of specifically and efficiently reacting with NHS esters. The PEG spacer enhances water solubility.
