0.5 M Ethylthiotetrazole solution (ETT in anhydrous acetonitrile)

5-Ethylthiotetrazole (ETT) is an efficient activator for use in chemical synthesis of either DNA or RNA.

ETT has excellent performance with respect to coupling times, coupling efficiency, consumption of phosphoramidites and reduction of n-1 impurities. ETT can be used for RNA synthesis with TBDMS, O-Methyl, TOM® or ACE® amidites.
