Used extensively in molecular biology research for synthesizing modified RNA molecules. It plays a crucial role in studying RNA function, structure, and interactions, particularly in the context of epigenetic modifications. This chemical is also employed in enzymatic reactions to incorporate methylated cytidine into RNA sequences, aiding in the exploration of RNA methylation processes and their biological significance. Additionally, it is utilized in the development of therapeutic RNA-based drugs and vaccines, where precise RNA modification is essential for efficacy and stability.
