A new highly hydrophobic 5'-hydroxyl protecting group (Tbf-DMTr) has been designed for the purification of synthetic oligonucleotides.Tbf-DMTr-oligonucleotides are strongly retained on RP-HPLC allowing a facile separation from truncated sequences.Subsequently the group can be removed in acidic conditions.The ultra-violet properties of Tbf-DMTr enable easy detection.The synthesis and purification of long oligonucleotides ( >100 mer) is envisaged.Keywords: RP-HPLC; 4-(17-Tetrabenzofluorenylmethyl)-4',4''-Dimethoxytrityl Chloride; Tbf-DMTr; DMTr; Protecting group; Oligonucleotide Synthesis.
