Used in RNA research and epigenetic studies due to its role as a modified nucleoside involved in dynamic RNA modifications. It serves as an intermediate in the oxidation pathway of 5-methylcytidine in RNA, helping scientists understand post-transcriptional gene regulation. Also utilized in the development of synthetic RNA molecules with tailored stability and function, particularly in mRNA-based therapeutics and vaccine platforms. Its aldehyde group allows for selective chemical labeling, enabling detection and pull-down assays in cellular RNA tracking.
