Detritylation什么意思
WebThe detritylation reaction is complex 125b, 132 and the amount of acid needed depends on the type of support used and increases with the ON chain length and is therefore not constant. The trityl cation generated during detritylation has an intense yellow/orange color, and it has been used to determine the end point of the detritylation reaction ... WebDetritylation of the support-bound 3'-nucleoside. At the beginning of oligonucleotide synthesis the first protected nucleoside is pre-attached to the resin and the operator selects an A, G, C or T synthesis column depending on the nucleoside at the 3'-end of the desired oligonucleotide. The support-bound nucleoside has a 5'-DMT protecting group ...
