Fast Deprotection Cap A contains tert-butylphenoxyacetyl aceticanhydride (TAC2O) in tetrahydrofuran, which ensures thedisplacement of tert-butylphenoxyacetyl (TAC) on guanine bases doesnot occur.
Preparation Note
Tetrahydrofurane / 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 tetrahydrofuran, 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.
