Used in the synthesis of oligonucleotides, particularly in the development of therapeutic agents and research tools. It plays a crucial role in creating modified RNA molecules, enhancing their stability and resistance to degradation. This chemical is essential in the production of antisense oligonucleotides, which are used to target specific RNA sequences for gene silencing or modulation. It is also employed in the study of RNA interference (RNAi) and the development of RNA-based drugs, contributing to advancements in treating genetic disorders, viral infections, and cancers.
