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 form of deoxycytidine, where the 4,4'-dimethoxytrityl (DMT) group protects the 5'-hydroxyl group, and the benzoyl group protects the N4 position. This protection is crucial during solid-phase oligonucleotide synthesis, ensuring that the correct sequence is assembled without unwanted side reactions. After synthesis, the protecting groups are removed to yield the desired oligonucleotide. This chemical is essential for creating custom DNA sequences used in PCR, gene editing, and other advanced biotechnological applications.
