General description
Deblock solution, containing dichloroacetic acid (DCA) in dichloromethane or Toluene, removes the dimethoxytrityl (DMT) protecting the group from the 5′ hydroxyl moiety of nucleotides already incorporated into the growing nucleic acid, prior to the addition of the next phosphoramidite. Removal of the DMT allows the unprotected 5′ hydroxyl moiety to react with a new phosphoramidite in a subsequent extension reaction.
Application
DCA Deblock (0.36M dichloroacetic acid in toluene) is suitable for the removal of 4,4Adimethoxytrityl (DMTr) protecting groups for the synthesis of antisense oligonucleotides in high yield and purity.

It is demonstrated that a solution of dichloroacetic acid in toluene removes dimethoxytrityl groups from the 5'-terminus of an antisense phosphorothioate oligodeoxyribonucleotide (ISIS 5132/CGP69846A) during synthesis on solid support cleanly and efficiently. It is therefore suggested to replace health hazardous

A theoretical study was performed to examine hydrogen and halogen bonds properties in gas phase and crystalline dichloroacetic acid (DCAA). The specific pattern of O-H∙∙∙O, C-H∙∙∙O, HCl, Cl∙∙∙O and Cl∙∙∙Cl interactions in DCAA dimers is described within the quantum theory
