This compound is primarily used in the synthesis of oligonucleotides, particularly in the field of molecular biology and genetic research. It serves as a protected nucleoside derivative, enabling the controlled assembly of DNA sequences during solid-phase synthesis. The phenoxyacetyl group protects the exocyclic amine, while the dimethoxytrityl (DMT) group safeguards the 5'-hydroxyl, ensuring selective reactivity during the coupling process. This compound is essential for producing custom DNA strands for applications such as PCR, gene editing, and sequencing. Its stability and compatibility with automated synthesizers make it a valuable tool in biotechnology and pharmaceutical development.
