Detritylation reagent
WebTraditionally dilute solutions of trichloroacetic acid (TCA, pK a 0.8) or dichloroacetic acid (DCA, p Ka 1.5) in dichloromethane (DCM) were used as detritylation reagent for ON synthesis. 125b, 132 Later, it was recognized that a high concentration of a weak acid (15% DCA in DCM) is more effective at driving detritylation toward completion than ...

WebFeb 1, 2009 · The most commonly used reagents today are dilute solutions (2–15%) of an organic acid, typically trichloroacetic acid (TCA, pKa 0.8) or dichloroacetic acid (DCA, pKa 1.5) in dichloromethane. WebMar 20, 2010 · The reagents are then left in the flowcell without mixing for 30 s (oxidation) and 60 s (detritylation). We define these periods (when the flow within the flowcell is stationary) as the dwell time. Finally, the reagents are drained from the bottom port (drain time), followed by washes using two flowcell volumes of acetonitrile (ACN).
