This chemical 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 trityl group protects the 5'-hydroxyl and the benzoyl group protects the N4-amino group during the chemical synthesis of DNA strands. This protection is crucial for ensuring that the reactions occur selectively at the desired positions without unwanted side reactions. After the synthesis, these protecting groups can be removed to yield the desired oligonucleotide sequence. This compound is especially valuable in the production of modified nucleosides and nucleotides, which are essential for studies involving DNA sequencing, gene therapy, and the development of antisense oligonucleotides. Its application is critical in advancing research in genetics, biotechnology, and pharmaceutical development.
