Used primarily in the synthesis of oligonucleotides, this chemical plays a crucial role in the production of DNA sequences. It serves as a protected nucleoside, ensuring the stability and specificity of the nucleotide during the assembly process. The benzoyl group protects the exocyclic amine, while the dimethoxytrityl (DMT) group safeguards the 5'-hydroxyl, allowing selective deprotection and coupling reactions. This compound is essential in automated DNA synthesizers, enabling the stepwise construction of custom DNA strands for applications in genetic research, diagnostics, and therapeutic development. Its use ensures high efficiency and accuracy in oligonucleotide synthesis.
