http://pubs.sciepub.com/wjce/6/1/4/index.html WebThe triphenylmethyl radical (often shorted to trityl radical) is an organic compound with the formula (C 6 H 5) 3 C. It is a persistent radical. It was the first radical ever to be described in organic chemistry. Because of its accessibility, the trityl radical has been heavily exploited.

WebA solution of trityl chloride (323 mg, 1.2 mmol) in dichloromethane (1 mL) was added to the reaction mixture and stirred at room temperature for 3 hours. The reaction mixture was quenched with water and extracted with dichloromethane. The organic phase was dried over anhydrous sodium sulfate and filtered. WebCrude synthetic oligonucleotides are purified by either trityl-on or trityl-off methodologies. In trityl-on practices, the final 5’ DMT protecting group is retained on the nucleotide and removed during purification, whereas for trityl-off, the 5’ protecting group is cleaved during the final cycle in the synthesis process.
