This chemical is primarily used in the synthesis of oligonucleotides, particularly in the field of molecular biology and genetic research. It serves as a key building block in the solid-phase synthesis of modified RNA strands, enabling the incorporation of 2'-O-methylcytidine into oligonucleotide sequences. This modification enhances the stability and nuclease resistance of RNA molecules, making it valuable for applications such as antisense oligonucleotide therapeutics, RNA interference (RNAi) studies, and the development of aptamers. Additionally, it is utilized in the production of synthetic RNA for research in gene expression regulation, diagnostics, and therapeutic drug development.
