Detritylation

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 …

Webacid to release the trityl group. In cartridge-based and HTP techniques, for complete detritylation, the consensus has been to add 2 % - 5 % of TFA and incubate at room temperature for five minutes. The rationale for the rather high acid concentration is effective detritylation requires one molecule of acid per monomer unit of oligonucleotide.
