UNSPSC Code:

Preparation Note
Acetic Anhydride / Tetrahydrofurane 9.1/90.9 (v/v)
Other Notes
Cap A solution, containing acetic anhydride and tetrahydrofuran (THF), is used after the phosphoramidite reaction/coupling step. This solution aborts chains bearing unreacted 5′hydroxyl groups due to failure of reaction with activated phosphoramidite (typically, 1 to 2% of growing oligonucleotide chains in each synthesis cycle). These unreacted 5′hydroxyl groups are capped with an acetyl group and thus rendered unreactive for subsequent synthesis steps.
