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 RNA sequences, enabling the creation of modified RNA strands with specific functions. The protective groups, such as DMT and TBDMS, ensure precise control over the coupling reactions, allowing for the stepwise assembly of RNA molecules. Its application is critical in the development of RNA-based therapeutics, including siRNA and antisense oligonucleotides, which are used to regulate gene expression and treat various diseases. Additionally, it plays a role in the study of RNA structure and function, aiding in the advancement of biotechnology and pharmaceutical research.
