TīmeklisETT (5-Ethylthio-1H-tetrazole) can offer more effective activation than tetrazole without crystallisation problems. In particular it has been shown to decrease the coupling times in both RNA synthesis (2) and DNA synthesis. BTT (5-Benzylthio-1H-tetrazole) activator is particularly useful in RNA synthesis with a view to reducing the longer ...
