General description

Fast Deprotection Cap 2 is an acetonitrile-based liquid reagent. It has a composition of Acetonitrile / TAC2O 100/5 (v/w).

Preparation Note

Acetonitrile / TAC2O 100/5 (v/w)

Other Notes

Fast Deprotection Cap A solution must be used for synthesis with Sigma-Aldrich′s TAC-protected phosphoramidites. Fast Deprotection Cap A solution, containing tert-butylphenoxyacetyl acetic anhydride (TAC2O) in acetonitrile, is used in place of Cap A solution to ensure that the displacement of tert-butylphenoxyacetyl (TAC) on guanine bases of the TAC-protected DNA and RNA phosphoramidites does not occur.
