Specific Separation of Products in Supported Oligonucleotide Syntheses Using the Triester Method

Abstract
The mixture of homologous nucleotide fragments usually formed during carrier‐oligonucleotide synthesis can be separated chromatographically so as to isolate the desired fragment, if the latter is protected at the 5′‐end with a hexadecyloxytrityl group (see (2) in the previous communication).
