As mentioned above, the naturally occurring nucleotides (nucleoside-3'- or 5'-phosphates) and their phosphodiester analogs are insufficiently reactive to afford an expeditious synthetic preparation of oligonucleotides in high yields. The selectivity and the rate of the formation of internucleosidic linkages is dramatically improved by using 3'-O-(N,N-diisopropyl phosphoramidite) deriva… Web3% Dichloroacetic Acid in Toluene (v/v) BioSyn™, Detritylation Solution, for DNA/RNA synthesis, CAS Number: 108-88-3,(674 Burdick & Jackson).Shop now or request a …
