WebDetritylation reagent 3% Dichloroacetic Acid in Dichloromethane (v/v), BioSyn™ for DNA/RNA synthesis, Burdick & Jackson™. Supplier: Honeywell Research Chemicals. Description: Burdick & Jackson® BioSyn® reagents & solvents for DNA/RNA synthesis. WebEven after long reaction times, excess of the reagent, and elevated temperatures, alkylation of the positions 2 and 3 was less than 11%, as confirmed by 13 C NMR spectroscopy (Figure 91). This selectivity is in the same range as for the unsubstituted trityl function. Moreover, the detritylation succeeds 20 times faster.
