Methyltetrazine-amido-PEG12-triethoxysilane functions as a heterobifunctional PEG linker composed of a methyltetrazine and triethoxysilane. Methyltetrazine is reactive toward trans-cyclooctenes and the additional methyl enhances the stability of the group. The triethoxysilane moiety is used for surface modification. The PEG12 chain improves the molecule's hydrophilicity.
